Assuming that you have a manifold mesh, then the border of the mesh are those edges which belong to only one polygon. Edges that are not on the border will belong to two polygons. The border vertices are the vertices that belong to the border edges. A naive way to find the border vertices is to iterate through all your edges, count how … blackpool crematorium records

WebJul 30, 2024 · Notice how the mesh has a quite poor triangulation, even though it filled the hole properly: filled = RepairMesh [reg, "HoleEdges"] So we'll rectify that by getting it back into 2D and re-discretizing it. We'll get the polygons and drop the z coordinates, then convert to a Graphics and finally call DiscretizeGraphics: COMSOL Multiphysics provides a wide selection of tools to control and generate mesh. We can start by discussing options for surface meshing, since we recommend to mesh faces first to verify adequate resolution and a high element quality. Note that a tool that meshes entities of a certain dimension also meshes … See more After setting up the flow conditions for a fluid flow model, COMSOL Multiphysics enables us to invoke physics-controlled meshing sequences. Such a sequence depends on the following aspects: 1. Physics property … See more When simulating CFD problems, we strive to create dense meshes in regions with large gradients. There are, however, cases when it is difficult to predict where the sharp gradients will appear. There are also time-dependent … See more Creating a good mesh for CFD problems is an art.
