TET10 / material_nonlinear_static	owner_accepted_experimental_bounded_use	code_aster	available	The straight-bar monotone TET10/TETRA10 correlation was accepted by the Owner for experimental internal use. A re-entrant combined-load campaign also passes automatically, but its Owner review remains open; general maturity stays experimental.
MITC4 / linear_static	stable	code_aster	available	Patch, locking, Cook, Scordelis, pinched cylinder and same-mesh conical-cutout correlations; Code_Aster closes the resultant check.
MITC4 / modal	stable	code_aster	available	Consistent mass and ten-mode Code_Aster correlation.

MITC3 / linear_static	stable	code_aster	available	Membrane, bending, hemisphere, Scordelis and pinched-shell evidence; active Code_Aster archive replaces obsolete versioned folder aliases.
MITC3 / modal	stable	code_aster	available	Modal invariants, free-free modes, curved-shell h-refinement, eigsh, same-mesh Code_Aster DKT correlation and dedicated 8x2/16x4/24x6 refinement are available; stable promotion remains subject to Owner review.
MITC3 / transient_newmark	stable	code_aster	available	First-mode time-history, energy, curved-shell time-step convergence, same-mesh Code_Aster DKT history and dedicated 8x2/16x4/24x6 refinement are available; stable promotion remains subject to Owner review.

MITC3 / laminate_linear_static	owner_accepted_experimental_bounded_use	code_aster	available	The flat symmetric [0/90/90/0] affine membrane patch is correlated with Code_Aster. The separate curved projected static scope is Owner-accepted with recommendations.
MITC3 / laminate_dynamic	owner_accepted_experimental_bounded_use	code_aster	available	Planar symmetric [0/90/90/0] modal/Newmark/harmonic responses are externally correlated on the same TRIA3 mesh with Code_Aster DST. Curved projected orientation remains outside the dynamic scope.
MITC3 / laminate_linear_static_curved	owner_accepted_experimental_bounded_use	code_aster	available	The Owner accepted the same faceted curved geometry with Code_Aster DST/TRIA3 and projected global reference vector as an experimental bounded static scope with recommendations. Ply stress, S13, damage, delamination and curved dynamic use remain outside the evidence.
MITC3 / laminate_dynamic_thin_planar	stable	internal_reference	available	The stable declaration is documented for the thin planar symmetric laminate only; automated dynamic evidence and the pending Owner review remain traceable, while curved, non-symmetric, damped and damaged use stays excluded.
MITC3 / laminate_static_curved_mixed_transverse	stable	internal_reference	available	The stable declaration is limited to the documented faceted curved mixed/transverse sub-domain; the axial-complete observable remains bounded and no general curved-laminate extrapolation is claimed.
BEAM2 / linear_static	stable	analytical	available	Timoshenko closed form and Code_Aster POU_D_E test route.
BEAM2 / modal	stable	code_aster	available	Six-mode axial and slender-transverse comparisons were accepted by the Owner on 2026-08-02.
BEAM2 / transient_newmark	stable	code_aster	available	Same mesh/time-grid axial and slender-transverse histories were accepted by the Owner on 2026-08-02.

CONTACT / linear_static	owner_accepted	code_aster	available	Bounded small-sliding normal-contact scope.
CONTACT / frictional_static	experimental	code_aster	available	Saturated sliding is correlated; adhesion remains non-comparable.
MITC4 / orthotropic_homogeneous_ply	stable	internal_reference	available	The stable declaration is limited to the homogeneous orthotropic one-ply shell domain and documented material orientations; it is not a ply-by-ply composite qualification and curved harmonic diagnostics remain excluded.
ORTHOTROPIC_SOLID / linear_static	stable	internal_reference	available	TET4/TET10 homogeneous orthotropic static behavior is covered by the controlled review and external-correlation test route; the scope excludes ply-by-ply composites, damage and singular stress acceptance.
ORTHOTROPIC_SOLID / modal	stable	internal_reference	available	The stable declaration is limited to the documented homogeneous orthotropic modal domain with the recorded mass and orientation conventions; nonlinear, damaged and ply-by-ply composite behavior remain excluded.
ORTHOTROPIC_SOLID / transient_newmark	stable	internal_reference	available	The stable declaration is limited to the documented homogeneous orthotropic Newmark domain with the recorded time-step and mass assumptions; nonlinear, damaged and ply-by-ply composite behavior remain excluded.
HEX8 / linear_static	accepted_for_release_0_2_3	internal_reference	available	HEX8 linear static release scope is covered by the internal campaign and bounded Code_Aster comparison; nonlinear, reduced-integration and large-scale claims remain excluded.
HEX8 / modal	accepted_for_release_0_2_3	internal_reference	available	HEX8 modal support is accepted only in the documented bounded internal domain; it is not a general large-scale or externally correlated modal qualification.
HEX8 / transient_newmark	accepted_for_release_0_2_3	internal_reference	available	HEX8 Newmark support reuses the common dynamic path and is accepted for the recorded bounded release scope; nonlinear dynamics and large-scale extrapolation remain excluded.
HEX8 / harmonic	accepted_for_release_0_2_3	internal_reference	available	HEX8 harmonic support is covered through the common analysis/backend contract in the bounded release domain; damping, nonlinear and multi-million-DOF claims are excluded.
HEX8 / material_nonlinear_static	owner_accepted_experimental_bounded_use	code_aster	available	HEX8 J2 is accepted only for the bounded one-element affine RQ-G08 correlation with Full Newton; multi-element, cyclic, physical-validation, contact and large-deformation claims remain excluded.
HEX20 / linear_static	accepted_for_release_0_2_3	internal_reference	available	HEX20 linear static release scope is covered by the internal campaign and bounded Code_Aster comparison; reduced integration, contact and large-scale claims remain excluded.
HEX20 / modal	accepted_for_release_0_2_3	internal_reference	available	HEX20 modal support is accepted in the documented bounded domain with external static-oriented comparisons; general large-scale modal qualification is not claimed.
HEX20 / transient_newmark	accepted_for_release_0_2_3	internal_reference	available	HEX20 Newmark support uses the common dynamic path and is accepted for the recorded bounded release scope; nonlinear dynamics and external dynamic correlation remain excluded.
HEX20 / harmonic	accepted_for_release_0_2_3	internal_reference	available	HEX20 harmonic support is covered through the common analysis/backend contract in the bounded release domain; nonlinear, damping and large-scale claims remain excluded.
HEX20 / material_nonlinear_static	owner_accepted_experimental_bounded_use	internal_reference	available	HEX20 J2 is retained as bounded experimental use only; the evidence does not qualify general plasticity, contact, damage or large-deformation behavior.
