From ddae39595fad6766580acee659c26e960dece3b5 Mon Sep 17 00:00:00 2001 From: VsevolodX Date: Tue, 1 Sep 2026 09:57:43 -0700 Subject: [PATCH 01/48] SOF-8043: add Gr/Ni(111) registry and separation simulation notebook MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reproduces the registry energetics of graphene on Ni(111) from Dahal & Batzill, Nanoscale 6, 2548 (2014): which high-symmetry registry is favourable, and how far the film sits above the surface. Two tiers. The film is placed at each of top-fcc, top-hcp, bridge-top and hollow — sites measured from the substrate's own top three Ni layers, and each registry labelled by where the second carbon sublattice lands — then scanned in z with MACE-MP + D3. A chemisorbing registry has two minima, so the comparison reads the chemisorbed branch and compares each registry at its own minimum; comparing at a shared height misranks them. The platform tier then computes one Total Energy job per registry at that geometry. The structure notebook additionally saves the base interface, which the simulation notebook loads by name: it previously saved only the empirically optimized variant. Verified in JupyterLite: top_fcc wins at 2.01 A (article: top-fcc at 2.1 A) and the hollow registry does not chemisorb.

Run All Cells continues past an error and the assertions were downstream, so it went unnoticed. Registries now carry the manuscript's own names and cover all four of its Fig. 1 configurations — hollow, atop/fcc, atop/hcp, bridge — with the figure itself embedded. Bridge is defined by its geometry rather than labelled by nearest site: one of its carbons is equidistant from two sites, so classifying it returned whichever the dict happened to list first. Claims match what the evidence supports. The two atop registries differ by a few meV per carbon, finer than this method resolves, so the check is on the atop family rather than on one of the two. The hollow registry's dispersion-bound distance is reported for context, not gated: MACE-MP + D3 places it near 4 A rather than graphite's 3.3 A. Two same-cell reference jobs (bare slab, free-standing film) now give an adsorption energy per carbon atom, with the cell, k-grid, cutoffs and smearing cancelling out of the difference. Also: the displaced variants are no longer written into uploads/, where load_material_from_folder's substring match over sorted filenames made them shadow the base material on a second run; degauss raised to 0.01 Ry for the metal; the scan-edge guard tests the sampled point rather than the interpolated minimum; dead label-mapping block removed; stray tildes in the introduction were rendering as strikethrough.

The figure puts a first-layer Ni under the midpoint of a C-C bond — the vertical bonds run through the centres of the surface atoms — while the code placed a carbon on the Ni-Ni midpoint, 1.9 A away, which also left that carbon equidistant from the fcc and hcp sites. The placement is now derived from the bond midpoint and verified rather than asserted, and it moves the bridge registry from 95 to 21 meV per carbon above atop/fcc, which is the shallow saddle it should be. starting_magnetization is indexed by position in ATOMIC_SPECIES, so the free-standing graphene reference would have started carbon with nickel's moment. The patch is now built per material by element, and a reference whose elements differ from the interface's gets its own workflow. The adsorption-energy references are off by default: they triple the job count of a run that is meant to finish one job unattended. Cutoffs drop to 40 Ry with an 8x density cutoff, per the GBRV guidelines already followed elsewhere in this repo. The scan-edge warning fired on every run, including where the minimum was properly bracketed by the point below it. It now fires only when the lowest chemisorbed sample is the first in the window, which is the case that actually means the well may lie outside it.

GBRV publishes its ultrasoft set as a 40 / 200 Ry pair, which is also the platform default, so that is what this uses. Each remaining parameter now states which of the three it rests on. The k-point divisions are a multiple of three because K sits at (1/3, 1/3) and has to lie on the grid, and dense because a metal's Fermi surface needs it. The starting moment is Ni's bulk value. D3 is on because the hollow registry has no chemisorbed minimum at all and is held only by dispersion. The MACE model size is a measurement, not a preference: medium at float32 finds no chemisorbed minimum and inverts the result. The SCF settings are grounded in the failure they fix. A first job stopped at "convergence NOT achieved after 100 iterations" with the total energy oscillating in its fourth decimal — charge sloshing, not divergence. Cold smearing leaves the free energy insensitive to degauss where the gaussian default does not; local-TF mixing is built for the long-wavelength charge oscillation a slab supports; a smaller mixing fraction and more iterations let the magnetic moment settle.

Phys. 13, 025001 (2011), Table 1, reached through the review: work of adhesion 0.81 / 0.77 / 0.31 J/m^2 for fcc / hcp / hollow at 2.16 / 2.17 / 3.26 A, with the atop carbon buckled outward. (The review's text quotes the hollow as 0.38; its source's table says 0.31.) Both tiers relax, because the buckling is one of the published numbers and no rigid placement can produce one. The fast tier follows the paper's scheme with MACE — bottom substrate layers fixed, same-cell relaxed references, registry re-verified after relaxation — and prints its comparison against Table 1 with an honest per-tier verdict: MACE-MP is PBE-trained, PBE is the functional the paper rejects for this interface, and the tier reports "no" with that reason rather than passing invented criteria. Where torch-dftd is unavailable (the browser), the tier says it is computing the GGA-level picture the manuscript describes as inadequate, and a registry with no minimum reports itself unbound instead of raising. The platform tier now runs the paper's method: LDA (pz, GBRV ultrasoft — the platform carries the LDA set for C and Ni), spin-polarized, with relaxation, and no dispersion correction, matching the paper's stated reason for choosing LDA over GGA. Each selected registry starts from its MACE-relaxed geometry; the two same-cell references are always submitted with it, so the work of adhesion is computable; an empty selection skips the tier, which is what the automated test uses. The convergence block is unchanged and now evidence-backed: gaussian smearing at default mixing stops at "convergence NOT achieved after 100 iterations" on this slab, while cold smearing with local-TF mixing converges the same structure in 62 (both outputs on cluster-001).

Most of what left was generality the notebook itself forbids: it asserts a 1x1 interface up front, so each Ni layer holds one atom — the z-clustering, top-layer averaging and species introspection collapse to a sort, a max, and one assert (Ni is species 1 in the interface and slab, so the magnetization index is fixed; the graphene reference gets the same workflow without the moment, ending the per-element-set dedup machinery). The parabola refinement died with the rigid scan's authority: relaxation supersedes interpolation, so a bracketed minimum is just the lowest non-edge scanned point. The k-grid loops are replaced by notebooks_utils' existing apply_scf_kgrid, which this notebook had re-implemented. The comparison cell drops its checks-dict scaffold for the established style: values beside the paper's, one plain verdict per tier.

Delaunay over the tiled surface layer, so it holds for any lattice and Miller index whose surface is flat within a tolerance, for films and for passivation. - relaxation: relax with the deepest layers held and, optionally, motion along z only, so a structure cannot slide out of its registry. Replaces a to_ase/FixAtoms/BFGS block written by hand in three notebooks already. - energetics: energy from a calculator, in-plane area, and work of adhesion in J/m^2 from same-cell references. - interface: film/substrate split, separation, corrugation. - compute: cluster selection that says what is wrong when none is registered, instead of IndexError from clusters[0] — the pattern in eight merged workflow notebooks. get_site_of returns None when two sites are equidistant rather than resolving by dict order; an ambiguous label is how a structure gets reported under the wrong registry. relax carries build metadata across the ASE round-trip, and get_interface_separation accepts the substrate elements, because the round trip otherwise strips what interface_get_part needs and measuring a relaxed interface raises. The Gr/Ni notebook uses all five: 534 code lines when this review round started, 376 now, with identical results to the digit. Also fixes two CodeRabbit findings on #364 — a registry with no relaxed structure is skipped before persistence, and cluster selection is guarded.

The tier now uses the platform's fixed_cell_relaxation workflow: one pw_relax unit, calculation='relax', and the rendered input carries nspin=2, starting_magnetization(1)=0.7, cold smearing, local-TF mixing, 12x12x1 and 40/200 Ry. The graphene reference runs nspin=1: it is non-magnetic, and QE needs a starting moment when nspin=2. - properties.get_for_job already returns the data records, so property_data[0]["data"]["value"] would have raised on the first energy. Energies are read with their units; the final structure is read back and separation and buckling compared, not only the work of adhesion. - The verdict is over what was selected, with the ordering check when all three registries are, instead of "no (1 of 3)". The fast tier's prose claimed the structure side as its strength; measured, it buckles the atop carbon toward the surface and sits 0.2 A too close. The notebook now says what it delivers: the registry set, the two-branch landscape and starting geometries, with its numbers beside the paper's. Also: a registry that relaxed onto other sites is dropped, not reported under the requested name; buckling is None where no carbon is atop, so the sign check cannot pass on an unsigned value; bottom layers are frozen by height, not by atom count; references are not uploaded when nothing will run; divergences from the paper are stated in the notebook; the verdict is printed once; get_compute has a unit test; one artifact name.

Both tiers now compare the sites the relaxed carbons occupy against one table of what each named registry is; a drifted row is excluded from the verdict and says so, and buckling is reported only where an atop carbon exists.

Checked on eight nets (fcc 111 at 1x1, 2x2 and a rotated cell; fcc 100 and 110; hcp 0001; rocksalt 100; bcc 100), which caught two bugs the fixture tests had not: atoms on or past the cell boundary were filtered rather than wrapped, and the periodic tiling was not centred on the home cell. Both fixed; a test on a substrate shifted by one whole cell pins them. - material/layers.py — layer grouping independent of basis order, and bottom-layer selection for holding substrate layers fixed. - mlff/relaxation.py — relax_material: ASE relaxation with fixed atoms and z-only motion, returning a copy with only the positions changed, so labels and build metadata survive; raises when not converged. material.py and mlff.py become packages; every existing import keeps working. Energies, interface parts, interlayer distance and area come from mat3ra.made functions that already exist. The notebook calls all of this instead of its own copies — identical results — and cluster selection is five inline lines again rather than a helper.

atoms: atomic operations plus one helper MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A registry on a supercell is a local statement — this film atom over that substrate site, the rest follow — so the anchor has to be something a person can name from what a viewer shows: an element near a coordinate, or an index. material/placement.py provides the pieces separately and one helper that combines them: - get_atom_indices(material, element) and get_atom_index(material, element, near) — "the Mo near (0.25, 0.25, 0.5)" — resolve to indices that describe_atoms lets you check before use. - place_over(interface, film_atom, substrate_atoms) — one film atom over one substrate atom (atop), two (bridge) or three (hollow), by the interface's own indices. Periodic images are chosen as the compact set that forms the site, not each atom's image nearest the first; atoms that are not neighbours of one another are refused against the layer's measured nearest-neighbour distance. - get_film_site_occupation(interface) — which named site each film atom sits on; the diagnostic for incommensurate films, where no single registry exists (Gr/Ni(001): 24 of 30 carbons on no site whichever anchor is moved). Parts are identified by labels, not build metadata, so relaxed and file-loaded structures work. The Gr/Ni notebook names its anchor carbon through the resolver instead of "coordinate 0".

The ASE relaxation keeps its place in notebooks_utils/mlff: an optimizer is not part of the structure library. The notebook's registry cell is four statements — the anchor carbon named by coordinate and radius, the site each registry puts it on, the resulting shift, and the occupation check that the other carbon landed where the registry's name says. Results are unchanged to the digit. config.yml's made profile now lists made's own requirements, so a made wheel registered in the JupyterLite bundle resolves them as the PyPI package would. mat3ra-made is pinned to made#298's commit until a release; the one temporary thing here.

The anchor carbon is named from the film's own measured height rather than a borrowed constant, the registry occupation check is an assertion instead of a print, and the DFT tier's site map is read from the relaxed structure's own Ni rather than the pre-relaxation substrate. Leftovers of the reverted made-extraction design (the empty material/ package, made's own layer-helper tests, the dead SQUARE_NET fixture, the dev-bundle-only config.yml edit) are removed with it.

charset=UTF-8 Content-Transfer-Encoding: 8bit The relaxation test built its fixture from an unpinned ZSL match: CI's transitive graph (scipy 1.15.3 vs 1.17.1 here; pymatgen and spglib are identical) resolves a different registry, breaking the "no in-plane force" assumption. The fixture now forces itself onto the atop_hcp registry the way cell 7 does — get_closest_site_id_from_coordinate_and_element + SurfaceSiteAnalyzer + interface_displace_part — and asserts get_film_site_occupation before deriving BOTTOM_NI and DISPLACED_CARBON from the built structure, no hardcoded indices. Printed verdicts (both tiers) now match PLAN-addendum-2026-09-01-paper-read.md §3 exactly: separation +/- 0.05 A, buckling sign-correct and within a factor of 2 of the computed 0.03 A target — not +/- 0.10 and sign-only. Cell 32 (55 lines) splits at the readers/usage seam, matching the sibling notebooks' cell-length convention; cell 11 imports get_atom_indices_by_layer from helpers, alongside the other two made#298 exports; `area` moves next to its only use. relaxation.py: the docstring pointed at a function neither made revision has; the slab-protocol justification belongs to the notebook cell that chooses the constraint, not a generic optimizer. `calculator` is now typed `ASECalculator`. Nits: duplicate imports in cells 8 and 10, two "what the alternative does not do" comments in the parameters cell. --- ..._position_graphene_nickel_SIMULATION.ipynb | 40 ++++++++++------ .../mat3ra/notebooks_utils/mlff/relaxation.py | 8 ++-- tests/py/unit/test_mlff_relaxation.py | 46 +++++++++++++++---- 3 files changed, 66 insertions(+), 28 deletions(-) diff --git a/other/materials_designer/specific_examples/optimization_interface_film_xy_position_graphene_nickel_SIMULATION.ipynb b/other/materials_designer/specific_examples/optimization_interface_film_xy_position_graphene_nickel_SIMULATION.ipynb index e91606f9c..6eb2ad859 100644 --- a/other/materials_designer/specific_examples/optimization_interface_film_xy_position_graphene_nickel_SIMULATION.ipynb +++ b/other/materials_designer/specific_examples/optimization_interface_film_xy_position_graphene_nickel_SIMULATION.ipynb @@ -102,7 +102,7 @@ "FOLDER = \"./uploads\"\n", "BASE_MATERIAL_NAME = \"Graphene_Nickel_interface\" # created by the companion structure notebook\n", "\n", - "# 4.

charset=UTF-8 Content-Transfer-Encoding: 8bit The previous fix built the fixture's registry with SurfaceSiteAnalyzer / get_atom_indices_by_layer / get_film_site_occupation to make it deterministic, but those three are made#298-only — confirmed against the released mat3ra_made-2026.8.26.post0 wheel, which has get_closest_site_id_from_coordinate_and_element but none of the other three. CI installs the released wheel, so that commit could never pass it (collection-time ImportError, not the original flaky-fixture failure). Row 0 (`MATERIAL` with no fixed atoms) was the only case that needed the built interface to actually be a symmetric high-symmetry registry; rows 1-3 hold under any starting geometry, since the z-only constraint fixes every atom's xy regardless of registry and the displaced-carbon rows only need *a* carbon and *a* bottom Ni. Dropped row 0, and BOTTOM_NI / DISPLACED_CARBON are now derived from plain element/label lookups on the built structure (both released-made APIs) instead of the registry-exact route. Verified against the actual released wheel: a from-scratch venv with mat3ra-made==2026.8.26.post0 and scipy==1.15.3 pinned to match run-py-tests' resolved version exactly — `pytest tests/py/unit` passes there too, not just against the made#298 dev worktree. --- tests/py/unit/test_mlff_relaxation.py | 52 +++++++++------------------ 1 file changed, 16 insertions(+), 36 deletions(-) diff --git a/tests/py/unit/test_mlff_relaxation.py b/tests/py/unit/test_mlff_relaxation.py index 027fe3e2b..6a610402f 100644 --- a/tests/py/unit/test_mlff_relaxation.py +++ b/tests/py/unit/test_mlff_relaxation.py @@ -2,24 +2,14 @@ import pytest from ase.calculators.emt import EMT from mat3ra.made.material import Material -from mat3ra.made.tools.analyze.other import get_closest_site_id_from_coordinate_and_element from mat3ra.made.tools.build.pristine_structures.two_dimensional.slab import SlabBuilder, SlabConfiguration from mat3ra.made.tools.calculate import calculate_total_energy from mat3ra.made.tools.convert.interface_parts_enum import InterfacePartsEnum -from mat3ra.made.tools.helpers import ( - SurfaceSiteAnalyzer, - create_interface_zsl_between_slabs, - get_atom_indices_by_layer, - get_film_site_occupation, -) -from mat3ra.made.tools.modify import interface_displace_part, interface_get_part +from mat3ra.made.tools.helpers import create_interface_zsl_between_slabs from mat3ra.notebooks_utils.mlff.relaxation import relax_material from mat3ra.standata.materials import Materials -# Built the same way as optimization_interface_film_xy_position_graphene_nickel.ipynb, cells 1.2-2.3, -# then put on the atop_hcp registry the way the SIMULATION notebook's cell 7 does — the ZSL search's -# cell choice is not pinned across environments, so the fixture asserts the registry it lands on -# instead of assuming the one the builder happens to return. +# Built the same way as optimization_interface_film_xy_position_graphene_nickel.ipynb, cells 1.2-2.3. _substrate = Material.create(Materials.get_by_name_first_match("Nickel")) _film = Material.create(Materials.get_by_name_first_match("Graphene")) _substrate_slab = SlabBuilder().get_material( @@ -42,7 +32,7 @@ use_conventional_cell=True, ) ) -_base_interface = create_interface_zsl_between_slabs( +MATERIAL = create_interface_zsl_between_slabs( substrate_slab=_substrate_slab, film_slab=_film_slab, gap=2.58, @@ -54,27 +44,18 @@ max_angle_tol=0.02, reduce_result_cell_to_primitive=True, ) -_substrate_part = interface_get_part(_base_interface, part=InterfacePartsEnum.SUBSTRATE) -_film_part = interface_get_part(_base_interface, part=InterfacePartsEnum.FILM) -_film_indices = [ - i for i, label in enumerate(_base_interface.basis.labels.values) if label == InterfacePartsEnum.FILM.value -] -_surface = SurfaceSiteAnalyzer(material=_substrate_part) -_film_cartesian = _film_part.clone() -_film_cartesian.to_cartesian() -_film_z = float(np.mean([c[2] for c in _film_part.coordinates_array])) -_anchor = get_closest_site_id_from_coordinate_and_element(_film_part, [1 / 3, 2 / 3, _film_z], "C") -_anchor_xy = np.array(_film_cartesian.coordinates_array[_anchor][:2]) - -MATERIAL = interface_displace_part( - _base_interface, displacement=list(_surface.get_displacement_to_site(_anchor_xy, "atop")) +# BOTTOM_NI and DISPLACED_CARBON are derived from the built structure, not pinned: the ZSL search's +# cell choice is not pinned across environments (an unpinned transitive resolves a different match), +# so a fixture that requires the registry ZSL happens to return is not something a test can rely on;

-0700 Subject: [PATCH 26/48] Fix review of bf0f5c11: IPython-free label_interface_parts, relaxed-Ni site map Move label_interface_parts to a leaf core/entity/material/interface.py (material.py re-exports it) so unit tests importing it no longer pull in IPython via material.py's io re-export chain, which was failing CI collection. film_sites_and_buckling now builds its SurfaceSiteAnalyzer from the interface's own labels instead of cell 7's unrelaxed surface, so both tiers read the site map against the relaxed Ni. Restore the one-line buckling_text helper (cell 11), used at its three call sites, in place of the repeated inline ternary.

Same defect made's own test suite hit and worked around by dropping the search entirely (see made's "Build the Gr/Ni(111) test fixture deterministically" / "Reuse the repo's ... fixture" commits): a searched cell cannot carry a pinned expectation. relax_material's contract is about constraints (fixed atoms don't move, along_z_only leaves xy untouched, non-convergence raises), not about Gr/Ni physics -- the interface path stays covered by scripts/verify_fast_tier.py and by made's own tests. Test it on a plain create_slab(Nickel) instead: Ni(100)'s own surface-relaxation force already exceeds RELAX's fmax (no ZSL, no artificial strain needed for case 0); one atom displaced in the other two cases gives the in-plane force to test drift vs. along_z_only. Module time is now ~3.8-5s (all import cost), down from the 6.75-8.93s the review measured and the construction-search cost that broke CI.

Do not re-add the filter: keep printing what was measured, but the message now says what happened without claiming exclusion, and registry_cell() marks the row -- the leftmost column shows the sites the job actually relaxed onto, not the nominal registry, in both the DFT-tier's own table (cell 32) and the final comparison table (cell 34). test_relaxation.py's case 0 relied on Ni(100)'s natural surface force, a 17% margin over fmax that would flip with half a percent of drift in standata's lattice constant. All three cases now displace the top atom deliberately (out-of-plane for case 0, in-plane for the other two) and test the constraint contract against a real force, not the data. The stale scripts/verify_fast_tier.py reference (that script lives in the task record, not this repo) is replaced with the SIMULATION notebook that actually covers the interface path, and the layer-grouping tolerance is named instead of a bare 0.5. notebooks_utils/mlff/ was a package whose only content, __init__.py, is byte-identical to main's mlff.py -- collapsed back to the module, the same move this PR already made once for material/. Nit: the bracket-minimum condition's second clause was a tautology (j is the argmin over the branch, so it is trivially <= its neighbors).

REGISTRY_COLUMN_WIDTH=18 (longest label + arrow + widest site pair, e.g. "atop_hcp→None/atop") keeps both tables' columns aligned. pr-body-364.md: the four "verdict" mentions predate 7161a20b's plain comparison table and one directly contradicted the Production Result paragraph below it ("the DFT tier has not yet been run" / "all three DFT-tier jobs finished"); rewritten to describe the current table, not a verdict that no longer exists. Size line corrected to the measured 9 files / +1095/-5 for api-examples. Live PR #364 PATCHed to match.

the structure notebook was deriving the same value implicitly from f"{FILM_NAME}_{SUBSTRATE_NAME} _interface", two separately-set parameters that happen to concatenate to the right string today but give no reader anywhere to see the two notebooks agree. Added BASE_MATERIAL_NAME as its own parameter and used it directly for interface_material.name; the optimized copy's derived name (f"{interface_material.name}_optimized_xy") is untouched since it now derives from the same explicit constant. Verified by deleting uploads/ and running the structure notebook's cells natively (skipping visualize/download_content_to_file, the way scripts/run_dft_tier.py does): the save cell writes uploads/Graphene_Nickel_interface.json, exactly what the SIMULATION notebook's load cell looks for. scripts/verify_fast_tier.py (index- remapped for 57 cells) then reproduces the identical registry table. --- ...imization_interface_film_xy_position_graphene_nickel.ipynb | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/other/materials_designer/specific_examples/optimization_interface_film_xy_position_graphene_nickel.ipynb b/other/materials_designer/specific_examples/optimization_interface_film_xy_position_graphene_nickel.ipynb index 21e9e9bea..60aaf1527 100644 --- a/other/materials_designer/specific_examples/optimization_interface_film_xy_position_graphene_nickel.ipynb +++ b/other/materials_designer/specific_examples/optimization_interface_film_xy_position_graphene_nickel.ipynb @@ -56,6 +56,8 @@ "# Material selection\n", "SUBSTRATE_NAME = \"Nickel\"\n", "FILM_NAME = \"Graphene\"\n", + "# canonical name the companion SIMULATION notebook loads by\n", + "BASE_MATERIAL_NAME = \"Graphene_Nickel_interface\"\n", "\n", "# Slab parameters\n", "FILM_MILLER_INDICES = (0, 0, 1)\n", @@ -196,7 +198,7 @@ " reduce_result_cell_to_primitive=REDUCE_RESULT_CELL_TO_PRIMITIVE,\n", ")\n", "\n", - "interface_material.name = f\"{FILM_NAME}_{SUBSTRATE_NAME}_interface\"\n", + "interface_material.name = BASE_MATERIAL_NAME\n", "\n", "# Visualize interface\n", "visualize_materials([interface_material], repetitions=STRUCTURE_REPETITIONS)\n", From a9332bdf49c75f70689437b3c2c987a545c5b5c8 Mon Sep 17 00:00:00 2001 From: VsevolodX Date: Mon, 14 Sep 2026 17:11:34 -0700 Subject: [PATCH 45/48] Move mlff/relaxation into notebooks_utils/calculate/, keep old imports as facades Mirrors made's tools/calculate/ split: notebooks_utils holds helpers that compute locally, distinct from core/api (platform), ipython (display) and pyodide (browser).
