Simulation of strong shock-interface interaction

摘要

It is found that a direct use of the GPM developed by Fedkiw et al may lead to inaccurate results during the simulation of a strong shock impacting on a material interface. In this work, we will propose a modified GFM (MGFM) with a predicted ghost fluid status. The MGFM is found to be far more robust than the original GFM and less problem-related.
