S.FEM is a free CAD design modeling and FEA, finite element analysis (GPU and CPU) software that will assist you in designing and analyzing 3D models easily, accurately, and quickly. It is also touch screen capable.
The S.FEM allows you to create your model using the available built-in 3D modeler tools, capable of doing many things such as creating mesh from triangles, creating solids from curves by sweeping, revolving, extruding, etc. For models that has been created using other 3D modelling software, you could import them to S.FEM for analysis purpose easily. S.FEM accepts models in many different popular CAD formats, such as the DWG, DXF, STL, STEP, IGES, OBJ, etc.
The Finite Element Analysis feature included with S.FEM is advanced and fast, it could do both linear and non linear analysis of various model, and the solver could run either on the highly parallel and very fast GPU (Graphics Card based calculation) , or, if you prefer more compatibility, the solver will also run on your multi-core CPU.
