Short description	PARODY_PDAF simulates incompressible MHD in a spherical cavity. In addition to the Navier-Stokes equations with an optional Coriolis force, it can also time-step the coupled induction equation for MHD (with imposed magnetic field or in a dynamo regime), as well as the temperature (and concentration) equation in the Boussinesq framework. It offers the possibility to perform ensemble assimilation experiments, being connected with the parallel data assimilation framework (PDAF) library. Based on a semi-spectral approach combining finite differences in radius and spherical harmonics, semi-implicit second-order time scheme
