In their own words
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.
GNU FisicaLab
GNU FisicaLab is a free desktop application for solving physics problems while handling the mathematical details. Its modules cover two-dimensional particle and circular kinematics, statics and dynamics, calorimetry, ideal gases, expansion, and thermodynamics. Statics and dynamics problems are described by constructing free-body diagrams. The interface supports SI and English unit systems. A grid chalkboard starts at 26 by 18 cells and can be enlarged in Preferences to 100 by 100. Data fields accept scientific notation, conversion factors, arithmetic, trigonometric functions, and square roots; parentheses cannot group operations. Online and downloadable documentation includes step-by-step examples. Source code is available from GNU FTP and mirrors, with previous Linux binaries and a Windows installer listed. GNU/Linux and BSD executable packages may come from distributions. FisicaLab is distributed under GNU GPL version 3 or any later version and provides no 3D visuals.
