The MuPhy II framework is now public and available on github and zenodo:
The muphyII code is a simulation framework for collisionless plasma physics and targeted at space plasmas in particular. The muphyII code utilizes a hierarchy of models with different inherent scales to address the separation of scales problem typically encountered in these plasmas. It allows stand-alone use of models as well as a model-based dynamic and adaptive domain decomposition and resorts to novel techniques for energy conservation, careful treatment of inner-domain model boundaries for interface coupling, and robust time stepping algorithms.
