In their own words
FEATool Multiphysics
FEATool Multiphysics is desktop software for engineering simulation, with tools to model and solve problems across heat transfer, mass transport, structural mechanics, fluid dynamics, and electromagnetics. Models can be built in 1D, 2D, or 3D, including axisymmetric configurations. Geometry tools support modeling and exchange in STEP, IGES, STL, and OBJ formats; meshes can be generated with built-in tools or Gmsh, Netgen, tetWild, and Triangle. FEATool connects its solvers with OpenFOAM, SU2, FEniCS, and redbKIT workflows. Interface actions map to MATLAB functions, and projects can be saved as MATLAB scripts or exported as Python scripts for FEniCS. Results can be exported to MATLAB, CSV, GMV, and VTK, or as interactive ParaView Glance and Plotly web models. It runs as a standalone app on Windows and Linux, or as a MATLAB toolbox on Windows, Linux, and Intel Mac; no standalone macOS app is available. A limited-functionality trial is offered, with full-feature trials requestable for 30 days.
