Description
We have developed a high-resolution massively parallel robust finite volume code termed SURYA to simulate the outer solar atmosphere (photosphere, chromosphere and corona). The code is based on high-order finite volume schemes for the Godunov-Powell form of the MHD equations and a well-balanced discretization to preserve magnetohydrostatic equilibria. Highlights include the simulation of Alfven waves and the ability of the code to handle real data sets. Ongoing work focuses on the inclusion of radiation by designing an efficient scheme for radiation MHD. Further validation with observed data sets from SOHO and HINODE is ongoing.
