WebIn principle, polynomial degree, mesh resolution and geometry are allowed to vary over different subdomains, but some interface compatibility properties are required. The operators over these trace-constrained exact finite element spaces commuting de Rham diagram are constructed in the context of projection-based interpolants. 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.
