The polyhedral mesh is derived directly from the tetrahedral mesh by forming polygons around each node in the tetrahedral mesh.
Slices through the meshes revealing volume elements are shown below. The duct geometry was decomposed into 6-faced blocks so it could support a hexahedral mesh as well as the more general tetrahedral and polyhedral meshes. This study focuses on a 3D backward facing step within a duct.
Polygon Surface Mesh: Backward facing step in a duct This study compares the volume element count, convergence, accuracy, and runtimes of the three different types of meshes for a simple duct. All rights reserved.Are you wondering how a polyhedral (dual) mesh compares to the equivalent tetrahedral and hexahedral meshes? Then you're in the right place.
