An Implicit boundary approach for viscous compressible high Reynolds flows using hybrid remeshed particle hydrodynamics method
TL;DR: An implicit boundary particle method with background mesh adaptation that uses a Brinkman penalisation to represent the boundary of the domain and a remeshed particle method to simulate viscous flow with high Reynolds numbers achieves an implicit approach for flow around complex boundaries/geometries simulation.
