Trending Fortran repositories on GitHub — ranked by total activity score (stars, forks, pushes, PRs) over the past month.
CEA computes the equilibrium composition of mixtures via free-energy minimization, and uses the resulting product concentrations to determine thermodynamic and transport properties. It includes a large database of species with thermodynamic curve-fit data, and can be used for rocket performance, detonation parameters, and shock-wave analysis.
OpenRadioss is a powerful, industry-proven finite element solver for dynamic event analysis
