CFX re-meshing Script

Rolanddr · January 19, 2017, 23:08

I am a student at the University of Houston, and I am working on an undergraduate thesis using CFX 17.1 to simulate the motion of a pig through a pipeline. I am modeling the pig as a rigid body and allowing the mesh to deform as the pig moves. I am monitoring the orthogonality angle of the mesh as an expression to interrupt the solver before I get an error for Negative volume in the mesh but I am having trouble finding information on how to write the script to call for a workbench re-mesh. I have even tried to manually extract the deformed mesh and re-mesh it with no success. Any help would be greatly appreciated.

I think there is an example of dynamic remeshing using ICEM on the ANSYS Customer webpage. Have you seen it?

I have not seen anything on the Ansys website that would help with this. I even just went back and looked unless I am looking in the wrong place

Hmm, I can't find it either. I recall there was one but it does not appear to be on the customer portal.

I would contact ANSYS support and try to get it. They have lots more examples.

A common example of dynamic remeshing using ICEM and CFX was discussed here a while ago. You can find the Tutorial here:
