PFC5 Geometry Import

Use this skill when aggregate shapes, molds, loading heads, wheel surfaces, or boundaries originate from CAD or node/element data.

Required Inputs

  • PFC2D/PFC3D 5.0 and target object;
  • source format, units, axes, scale and coordinate origin;
  • node/element/polyline schema and indexing convention;
  • topology requirements and downstream PFC5 command path;
  • legal status of any external converter.

Workflow

  1. Prefer simple native PFC5 walls for boxes, platens, cylinders and test heads.
  2. For external geometry, freeze units/axes and convert to transparent CSV/text. PFC5 native geometry import supports its geometry format plus partial DXF and text/binary STL; wall import can consume supported files or a geometry set.
  3. Validate duplicate IDs, missing node references, degeneracy and extents with scripts/validate_geometry_csv.py.
  4. Materialize geometry in a private case and inspect it before particle filling.
  5. Test one wall/contact or one clump template before bulk generation.
  6. Record the exact external-to-PFC5 handoff and runtime probe.

Read geometry-contract.md for CSV schemas.

Working Rules

  • Old executables are optional external tools, never package dependencies.
  • A valid file does not prove correct scale, orientation, manifold quality or contact normals.
  • Do not use wall import ... nothrow as a default repair strategy: PFC5 may ignore offending facets, leaving an incomplete wall. If used diagnostically, audit the rejected facets and final wall closure explicitly.
  • Do not translate newer-major geometry commands into PFC5 by keyword substitution.
  • Preserve original geometry and generated intermediate files separately.

Output Contract

Return source/provenance, units/axes, validated CSVs, extents/topology report, PFC5 handoff, contact probe and runtime status.

Local Contents

  • references/geometry-contract.md — portable node/element/polyline schemas.
  • scripts/validate_geometry_csv.py — deterministic geometry validator.
