Coverage
Linear and nonlinear structural mechanics, thermal and thermomechanical analyses, contact, and modal extraction. Material cards generate from typed constitutive choices in the CaseSpec.
The .inp deck
The adapter writes a CalculiX-format input deck with *HEADING, *NODE, *ELEMENT, *MATERIAL, *BOUNDARY, *STEP, *STATIC/*DYNAMIC, and *OUTPUT blocks. Mesh *INCLUDE indirection keeps the deck small and the mesh independently re-materializable.
Loads, constraints, contact
Loads, displacement constraints, MPCs, and contact pairs are typed in the CaseSpec and projected into deck cards. Named selections become NSET and ELSET entities so a CAD-update mesh-regeneration doesn't break BCs.
QoIs you can extract
Stress (von Mises, principal), strain, displacement, reaction force, contact pressure, and modal frequencies are all typed QoIs with units, scope (region/node/element), and tolerance. The CalculiX *OUTPUT, FREQUENCY block is generated to record exactly what's needed — no more, no less.
NAFEMS-style review
Standards packs (e.g., ASME BPV VIII-2 Linear Elastic Review Pack) add mandatory extracts, signature blocks, and algorithm references that the report builder enforces before publication.
