freecad-fem-check

Build or audit reproducible preliminary FreeCAD FEM checks with explicit solver capability detection, analytical baselines, boundary-condition review, reaction equilibrium, mesh sensitivity, singularity handling, and evidence-limited conclusions. Use for FreeCAD plus CalculiX or Gmsh linear-static studies, for diagnosing suspicious stress or displacement fields, or for deciding whether a proposed contact, nonlinear, FDM, creep, fatigue, or snap-fit analysis is outside the validated workflow.
