: Detail on how various elements (e.g., membrane triangles, composite plates) are derived and their inertia properties.

: The Verification Guide often refers back to these theoretical solutions to prove that the solver's results are valid compared to known analytical benchmarks. Documentation Ecosystem NX Nastran Theoretical Manual
