A swept‐intersection‐based remapping method in a ReALE framework

Abstract: SUMMARY A complete reconnection‐based arbitrary Lagrangian–Eulerian (ReALE) strategy devoted to the computation of hydrodynamic applications for compressible fluid flows is presented here. In ReALE, we replace the rezoning phase of classical ALE method by a rezoning where we allow the connectivity between cells of the mesh to change. This leads to a polygonal mesh that recovers the Lagrangian features in order to follow more efficiently the flow. Those reconnections allow to deal with complex geometries and hi… Show more

“…Unfortunately, the flux based algorithm of [21] implicitly assumes the topology of the mesh is not changing, only the geometry. Extensions to the flux-based remap have been presented that do not assumed a fixed topology, for instance [7,10], but the problem of remapping staggered or subzonal data has not yet been addressed. For this paper, we focus on geometric overlay-based remapping.…”
