Element	Analysis	Recorded status	Scope details
MITC4	Linear static	Qualified bounded	Read limitations MITC4 schematic Isotropic constant-thickness MITC4 linear static, small-displacement/small-rotation, executed mechanics, patch, equilibrium, drilling and reference-mesh scope only. No variable thickness, composite, nonlinear, contact, buckling or large-rotation claim; Cook remains a bounded trend warning. Historical source note: Combination state is inherited from aggregate 0.2.6 records; no new execution evidence is implied. G05 is PASS_WITH_LIMITATIONS; no comparable independent external deck is recorded for MITC4. Family-specific requalification is scheduled in G04.

MITC4	Modal	Experimental	Read limitations MITC4 schematic No tolerance relaxation or numerical-core change is authorized. Historical source note: Combination state is inherited from aggregate 0.2.6 records; no new execution evidence is implied. G05 is PASS_WITH_LIMITATIONS; no comparable independent external deck is recorded for MITC4. G05 is PASS_WITH_LIMITATIONS: modal evidence covers eight internal family rows, while external correlation remains bounded and family-incomplete.

MITC4	Newmark transient	Qualified bounded	Read limitations MITC4 schematic Verified one-mode, undamped free-vibration Newmark average-acceleration temporal scope with the declared 20/40/80 steps-per-period study only. The spatial mode is from QF Solver; forced, nonlinear, broadband, composite and curved-dynamic claims remain excluded. Historical source note: Combination state is inherited from aggregate 0.2.6 records; no new execution evidence is implied. G05 is PASS_WITH_LIMITATIONS; no comparable independent external deck is recorded for MITC4. G05 is PASS_WITH_LIMITATIONS: Newmark refinement and analytical evidence are complete, while external correlation remains bounded and family-incomplete.

MITC4	Harmonic	Qualified bounded	Read limitations MITC4 schematic Verified first-mode, seven-frequency, mass-proportional damping FRF scope only. Broadband coupling, thick-shell, composite, nonlinear and alternate damping-model claims remain excluded. Historical source note: Combination state is inherited from aggregate 0.2.6 records; no new execution evidence is implied. G05 is PASS_WITH_LIMITATIONS; no comparable independent external deck is recorded for MITC4. G05 is PASS_WITH_LIMITATIONS: harmonic refinement and analytical evidence are complete, while external correlation remains bounded and family-incomplete.

The versioned registry governs these combination statuses. Any linked Code_Aster case is a separate frozen linear static correlation, not qualification of every row.

Before you solve

Check orientation, geometry, loads, materials, the selected solver and required observables. Refinement does not repair an invalid Jacobian or establish an unsupported material route.
