Parallel unstructured mesh adaptation using iterative remeshing and repartitioning

Abstract : Mesh adaptation has proven to be a powerful tool for increasing the accuracy ofnumerical simulations whenever the solution exhibits strong non-uniform features over the com-putational domain. Sequential remeshing currently represents a bottleneck for parallel solvers. Tothis aim, we present a parallel remeshing algorithm that enables the reuse of existing sequential remeshing libraries, a non-intrusive linkage with third-party solvers, and an efficient exploitationof distributed parallel environments. The numerical procedure is implemented in the open sourceParMmg software package.
