Online Structural Analysis & Finite Element Solver
What would you like to build?
Structural analysis, directly in your browser
Vibe-FEM is a free online structural analysis tool and browser-based finite element solver. Build a model, assign materials, supports and loads, and inspect the response without installing desktop software. Manual modeling and solving are available directly in the browser.
Truss analysis Model 2D pin-jointed structures and examine nodal displacements, support reactions and member axial forces. Interactive editing makes it easy to adjust geometry and explore different loads.
Frame analysis Analyze 2D beams and frames, including inclined roller supports. View displacements, reactions, axial forces, shear forces and bending moments to understand how the structure carries its loads.
Solid analysis Mesh 2D solid models for linear elastic finite element analysis. Inspect displacement and stress fields, then check support reactions and overall force and moment balance.
Cross-section analysis Calculate area, centroid, second moments of area and principal axes. Create custom cross-sections and align them to their principal axes for use in frame models.
Optional AI-assisted finite element modeling turns a written description into an editable model that you can review before solving. Connect your own provider API key to use AI features; provider usage costs may apply.
