Element	Analysis	Recorded status	Scope details
HEX8	Linear static	Qualified bounded	Read limitations HEX8 schematic Inherited evidence within the recorded scope; no new promotion is implied. Historical source note: Combination state is inherited from aggregate 0.2.6 records; no new execution evidence is implied. G05 internal quantitative and analytical evidence is present; comparable independent external deck remains pending. Family-specific requalification is scheduled in G04.

HEX8	Modal	Qualified bounded	Read limitations HEX8 schematic Inherited evidence within the recorded scope; no new promotion is implied. Historical source note: Combination state is inherited from aggregate 0.2.6 records; no new execution evidence is implied. G05 internal quantitative and analytical evidence is present; comparable independent external deck remains pending. G05 is PASS_WITH_LIMITATIONS: modal evidence covers eight internal family rows, while external correlation remains bounded and family-incomplete.

HEX8	Newmark transient	Qualified bounded	Read limitations HEX8 schematic Inherited evidence within the recorded scope; no new promotion is implied. Historical source note: Combination state is inherited from aggregate 0.2.6 records; no new execution evidence is implied. G05 internal quantitative and analytical evidence is present; comparable independent external deck remains pending. G05 is PASS_WITH_LIMITATIONS: Newmark refinement and analytical evidence are complete, while external correlation remains bounded and family-incomplete.

HEX8	Harmonic	Qualified bounded	Read limitations HEX8 schematic Inherited evidence within the recorded scope; no new promotion is implied. Historical source note: Combination state is inherited from aggregate 0.2.6 records; no new execution evidence is implied. G05 internal quantitative and analytical evidence is present; comparable independent external deck remains pending. G05 is PASS_WITH_LIMITATIONS: harmonic refinement and analytical evidence are complete, while external correlation remains bounded and family-incomplete.

HEX8	Linear buckling	Experimental	Read limitations HEX8 schematic EXPERIMENTAL does not mean QUALIFIED_BOUNDED, normal-use or production-ready. No general Euler prediction or convergence claim is made; WP06/WP06B Euler and convergence FAIL records remain visible. No certification, imperfections, nonlinear/post-buckling, plasticity, arbitrary-mesh, universal-accuracy, multi-mode or mixed-mesh claim. No external correlation claim; current comparable Code_Aster/CalculiX evidence was unavailable. HEX8R, SRI, B-bar and hourglass formulations are excluded. Historical source note: G14 explicitly retains HEX8 buckling as more-evidence-required. G05 internal quantitative and analytical evidence is present; comparable independent external deck remains pending. No nonlinear collapse claim; 0.2.6 maturity extension is pending.

HEX8	Nonlinear load control	Experimental	Read limitations HEX8 schematic Inherited evidence within the recorded scope; no new promotion is implied. Historical source note: Combination state is inherited from aggregate 0.2.6 records; no new execution evidence is implied. G05 internal quantitative and analytical evidence is present; comparable independent external deck remains pending. Maturity extension and multi-family correlation are scheduled separately.

HEX8	Geometric nonlinear static	Experimental	Read limitations HEX8 schematic Inherited evidence within the recorded scope; no new promotion is implied. Historical source note: Combination state is inherited from aggregate 0.2.6 records; no new execution evidence is implied. G05 internal quantitative and analytical evidence is present; comparable independent external deck remains pending. Only bounded TET4/HEX8 Total-Lagrangian elasticity is qualified; high-order and finite-kinematic J2 remain non-qualified. Analysis formulation and scope → Versioned source record ↗

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.
