Meshing Controls: Geometry- and Mesh-Based Defeaturing
ANSYS Meshing allows for geometry- and mesh-based defeaturing in a variety of ways. In patch-independent and MultiZone meshing defeaturing is integrated into the meshing process and driven by a tolerance. Virtual topologies are used to merge faces and edges prior to meshing so that the mesher ignores the individual faces and edges. Pinch controls are used to merge mesh nodes in close proximity after meshing using a given tolerance. Each of these approaches has some unique strengths.
