Solar Wind Simulations

We have developed a two-dimensional hydrodynamic model of the global structure of the heliosphere which includes a population of interstellar neutral hydrogen atoms which interact with both the solar wind and interstellar plasmas via charge-exchange collisions. Both ions and neutrals are treated as fluids.

The code runs on the Cray T3D parallel supercomputer at JPL at a sustained speed of about 8 gigflop/s. The code uses the mesh spectral archetypes developed by the NSF Center for Research on Parallel Computation.
