| Abstract: |
The structure is described of the Multi-Scale FLUid-Kinetic Simulation Suite (MS-FLUKSS), which is developed as a tool for modeling discontinuous flows of partially ionized plasma. The challenges which are addressed in the suite include the necessity of fine resolution of discontinuities in timedependent magnetized flows and efficient modeling of the neutral atom transport with an ion–atom mean free path comparable with the distances between major heliospheric discontinuities. The major constituent blocks of this suite are the following: an adaptive mesh refinement module to solve the ideal MHD equations with multiple discontinuities, multi-fluid and kinetic modules to solve the Boltzmann equation for the atom transport, and a module to calculate the cosmic ray transport. We show recent results on the code performance, scalability, and testing. The application of the suite to the calculation of a complex flow of partially-ionized plasma occurring when the solar wind collides with the local interstellar medium is discussed. |
