Known limitations

Every result is bounded by the element family, formulation, mesh quality, loading, boundary conditions, material model and solver route used to produce it.

  • WEDGE6 static is experimental. WEDGE15 and PYRAMID5 are not supported.
  • Mixed TET/WEDGE/HEX end-to-end workflows are not qualified.
  • HEX8R, SRI, B-bar and hourglass-control production paths are deferred or research-only.
  • Finite-kinematic J2 remains experimental and is not a production claim.
  • General nonlinear, contact-with-friction and finite-sliding routes remain experimental, bounded or outside the qualified scope.
  • 5M Gold and deeper 10M scaling analysis are deferred. The 10M result is a bounded C3 capacity/solve observation, not a universal scaling claim.
  • Optional PETSc/MPI and SLEPc routes require their external runtimes. Their absence must be reported explicitly and does not invalidate core import.
  • Code_Aster comparisons are limited to comparable recorded cases. CalculiX results are NOT_COMPARABLE where conventions, integration or observables do not match strictly.
  • macOS and some declared Python versions are not directly verified locally; they are not claimed as tested without CI or reproducible evidence.
  • No certification, universal physical validation, industrial equivalence or hardware-independent performance claim is made.
