WebAug 25, 2024 · Adaptive meshing is a method of refining the mesh of a simulation based on the solution. This scheme in Ansys Fluent enables you to start from a very coarse mesh and dynamically refine high-gradient regions. Dynamic mesh adaption can be used in combination with the polyhedral unstructured mesh adaption (PUMA) method. WebAdaptive mesh refinement works with the mesh and equations defined in the domains (interior) of the geometry and does not consider meshes and equations on lower dimensions, such as surface meshes in shell models. In solid geometries, the adaptive mesh refinement of the interior mesh usually affects the surface mesh. closed area permit hk
