Abstract:

Tech-X in collaboration with the University of Washington has investigated techniques for improved fully electromagnetic multi-fluid simulation modeling capability on structured and unstructured grids. Among the success of this project include the development of an oracle for predicting the regions of validity of various plasma models, implementation of nodal discontinuous Galerkin methods MUSCL and k-exact finite volume schemes on unstructured meshes for multi-fluid simulations. During the phase I electric field diffusion for divergence cleaning was implemented and demonstrated to work much better than hyperbolic cleaning in the presence of space charge. Finally, we performed demonstrations of algorithms on complex problems and unstructured domains, including magnetic reconnection and field reversed configuration FRC formation.
