With ICEM CFD’s Replay feature, you can analyze geometry variations. Changes in length, width and height of specific geometry features are known as parametric changes. Parametric changes do not affect the block topology, so the Replay function can automatically generate a topologically similar block model that can be used for the parametric changes in geometry. If any of the Direct CAD Interfaces are used, all geometric parameter changes are performed in the native CAD system.
To generate a Replay file:
From File > Replay Scripts, activate the recording of the commands needed to generate a custom meshing process. All of the steps in the mesh development process are recorded, including blocking, mesh size, edge meshing, boundary condition definition, and final mesh generation.
Make a parametric change in the geometry and then replay the recorded file on the changed geometry. All steps in the mesh generation process are automated from this point.
