CalculiX · running as WebAssembly

Real physics, solved in this tab

A single steel bar under 1 MPa of tension has an exact answer: no mesh to refine, no reference solution to trust. Press run and CalculiX, the real GPL finite-element solver, computes it live in your browser. The result below is checked against the closed-form answer to twelve decimal places.

This is the same ccx.wasm that ships inside FreeCAD's FEM workbench, not a demo built for this page. Run the full workbench, mesh your own part, and solve it, free, at freecad.virtastic.app.
