An effective preconditioning strategy for volume penalized incompressible/low Mach multiphase flow solvers
Ramakrishnan Thirumalaisamy, Kaustubh Khedkar, Pieter Ghysels +1
The volume penalization (VP) or the Brinkman penalization (BP) method is a diffuse interface method for simulating multiphase fluid-structure interaction (FSI) problems in ocean en…
