Hello everybody,

i am starting to work with icem/cfx these days and i arrived at a problem with surfaces insides of a (fluid) volume. How can I define them to be ignored (in icem or cfx-pre)? They should be part of the volume without any boundaries (no wall like it is posed by default). They were just necessary for the density of my unstructured tetra-mesh creation. In cfx-pre they are automatically posed as primitive 2D and I can't delete them.

Thanks for help, sincerely,

Johannes

You can try defining them as thin surfaces within Pre. There is a checkbox in the wall boundary condition definition to set this.
