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.
FeenoX
FeenoX is free, open-source computational engineering software for solving mathematical and engineering problems, including work across computers in parallel. It handles ODEs and DAEs, along with finite-element problems such as heat conduction, thermo-mechanical analysis, modal analysis, neutron diffusion, and neutron transport. Users describe problems in self-descriptive, English-like plain-text input files, so changes do not require recompiling. FeenoX reads Gmsh meshes and writes results in Gmsh MSH or ParaView VTK/VTU formats. It uses GNU GSL, SUNDIALS, PETSc, and SLEPc for computational tasks, and supports MPI parallelization. Installation options include Debian or Ubuntu packages, source tarballs, the GitHub repository, and generic statically linked GNU/Linux binaries. Ubuntu packages are available from version 25.04 onward. The generic binaries omit MUMPS and MPI and use basic optimization flags. FeenoX has no graphical interface, targets GNU/Linux, and is not expected to run in Windows. Browser access is available through interfaces such as SunCAE and CAEplex.
