QF Solver 0.2.5a0

QF Solver 0.2.5a0

Highlights

• Bounded qualification of small-strain J2 on TET4, TET10, HEX8, and HEX20.
• Bounded Total-Lagrangian elasticity on TET4 and HEX8.
• Bounded sparse linear buckling.
• Bounded frictionless contact.
• Robustness, failure-mode, and performance qualification.
• Stronger V&V provenance and release traceability.

Verification

• 1,719 passed / 0 failed qualification regression.
• 88.37% reference coverage.
• 64/64 external-correlation checks PASS.
• GitHub CI green on Linux and Windows with Python 3.10 and 3.13.
• Documentation evidence and full engineering campaign PASS.

Important limitations

• Arc-length remains experimental and not qualified.
• Finite-kinematic J2 and coupled nonlinear workflows remain experimental.
• Friction is outside the 0.2.5a0 release scope.
• No claim of general physical validation, certification, or industrial-solver replacement.
