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.
