Ansys Meshing - Mesh Copy Control
Written by cfd.ninja
When a model contains repeated bodies, meshing each one separately wastes time and produces slightly different meshes for identical parts. Copying the mesh solves both problems at once.
The requirement is topological: the source and target bodies must be equivalent, related by a translation or a rotation. Tube banks, arrays of fins, the blades of a wheel and repeated channels are the usual candidates.
Beyond the time saved, there is a numerical benefit. Identical parts end up with identical cells, so any difference you see between them in the results comes from the flow rather than from the mesh.
