STRUPHY - NMPP Codes

STRUPHY (STRUcture-Preserving HYbrid code) is a Python package for solving partial differential equations arising mainly - but not exclusively - in plasma physics. It provides off-the-shelf models for Maxwell’s equations, magneto-hydrodynamics (MHD), multi-fluid models, Vlasov-Poisson and Vlasov-Maxwell kinetic models, drift-kinetic models, and MHD-kinetic hybrid models, all built on structure-preserving finite element methods. Models run in parallel via MPI and OpenMP, with compute-intensive kernels transpiled to Fortran/C through pyccel for near-native performance from within Python.
