Live FEA · AI assisted

One beam. Solved as you touch it.

Place supports and loads, drag them along the beam, pull a force arrow to change its size. A finite element solver runs in your browser on every move. Switch to 3D part to load an example or upload your own STEP file: it is meshed and solved on our own solver server. Or just describe the problem to the AI and let it build, solve and explain the model.

Your files. STEP files you upload and parts built here are kept only on our solver server in the EU, never shared, and deleted automatically: anything older than 3 hours every hour, and everything every night.

About the solver. Linear elastic Euler–Bernoulli beam finite elements, consistent nodal loads, exact for point and uniform loads. Stresses come from beam theory: bending stress M·c/I, parabolic shear, combined as von Mises. Buckling, lateral-torsional stability, plasticity and code checks are not included. A demonstration, not a design calculation.
