moving mesh VS multigrid
Hi guys!
What is the difference between moving mesh and multigrid? Thanks! |
moving mesh uses non-fixed mesh that can be because of moving boundaries or adaptive mesh. multigrid uses different meshes on a same domain with different sizes and the solver moves between them. it causes the errors to distribute faster and results in a faster convergence.
