Free !full! Autodesk Inc. Robot Structural Analysis Link
I started using the free version of Autodesk Robot Structural Analysis for academic and personal projects, and I’ve been genuinely impressed. It handles complex 3D FEM modeling, code checks (AISC, EC, etc.), and dynamic analysis with ease. The interface is similar to Revit and AutoCAD, so if you're familiar with Autodesk products, the learning curve isn’t too steep.
