Ferro
Ferro is Qubis's structural finite element (FEM) solver — linear static,
modal, buckling and prestressed modal analysis of solid parts. Drive it from Qubis (a dedicated
3D viewport) or ferro-cli (scripts and CI) — both produce the same
FerroRequest and solve identically.
All Ferro inputs are SI units (Pa, N, m, K, kg, Hz). There is no unit conversion — if you feed in the wrong units, the solve runs anyway and produces silently wrong results.
