FESA Reference Artifacts

This folder stores Abaqus input files and solved reference result artifacts used to verify FESA.

Abaqus is not run by the repository validation flow. Files here are treated as stored numerical references after they are accepted.

Initial Accepted Files

Case	Input	Result Artifact	Notes
`quad_01`	`quad_01.inp`	`quad_01_displacements.csv`	Abaqus/CAE Learning Edition 2024 source input; displacement CSV has 121 nodal rows

Displacement CSV Format

*_displacements.csv files use Abaqus-exported nodal displacement columns:

Node Label, U-U1, U-U2, U-U3, UR-UR1, UR-UR2, UR-UR3

Mapping to FESA:

CSV Column	FESA Component
`Node Label`	node id
`U-U1`	`UX`
`U-U2`	`UY`
`U-U3`	`UZ`
`UR-UR1`	`RX`
`UR-UR2`	`RY`
`UR-UR3`	`RZ`

Compatibility Notes

Stored Abaqus inputs may contain features outside the current FESA Phase 1 parser subset. Preserve the original files and document unsupported features instead of editing them in place.

quad_01.inp currently includes TYPE=S4R, Part/Assembly/Instance, *Density, and NLGEOM=YES. These are stored for reference provenance and future compatibility work; they are not Phase 1 parser acceptance requirements unless docs/ABAQUS_INPUT_SUBSET.md and docs/ADR.md are updated.
