WebMesh quality can be improved by converting the tetrahedral cells to polyhedral cells in CFD solvers (ANSYS FLUENT, Star CCM) For poor quality mesh, the solutions can be obtained by controlling the relaxation factor or selecting near-wall gradient schemes; Try to keep at least three-element in narrow gaps which is a shadow or wake region. Web1 de jan. de 2015 · Three methods are investigated to remove the concavity at the boundary edges and/or vertices during polyhedral mesh generation by a dual mesh method. The non-manifold elements insertion method is the first method examined. Concavity can be removed by inserting non-manifold surfaces along the concave edges and using them as …
WebCreate Dual Mesh operation modifies mesh in such a way that existing cell centers become new nodes and existing nodes become new cell centers. This operation is usually used to convert tetrahedral meshes into polyhedral meshes. Polyhedral meshes usually offer significantly reduced computational time with only minimal reduction in solution accuracy.
