Summary
In this work, we introduce a new method for generating Lagrangian computational meshes from Eulerian-based data. We focus specifically on shock physics problems that are relevant to Eulerian-based codes that generate volume fraction data on a Cartesian grid. A step-by-step procedure for generating an all- hexahedral mesh is presented. We focus specifically on the challenges of developing a parallel implementation using the message passing interface (MPI) to ensure a continuous, conformal and good quality hex mesh.
