Hello,
I have a problem with CFX. I am doing a free surface problem around a surface piercing cylinder. I have drawn the problem in Creo Parametric and saved as a .IGES file. It imports fine in to the geometry part of CFX. The problem is when I go to the setup the geometry cannot be seen. And also I do not know how I break the one surface in to several surfaces as they are needed to label boundary locations to make things a little easier. I am following the flow over a bump VOF tutorial and it doesn't mention anything about this.
Any help would be much appreciated.
Thanks

Your questions are geometry and meshing questions, not CFX questions. This means the CFX tutorials will not be relevant. You can find relevant geometry and meshing tutorials on the ANSYS customer web page.

you have to start with workbench. Start a new CFX simulation, then work your way top to bottom.
Surfaces, easier to split them in a CAD program. Then import into Design Modeler. Create names selections. These will then follow through the mesher, Pre and Post. If you name Inlet Inlet and Outlet Outlet, the Pre will even suggest to use them for the boundary condition. Unless you are legasthenic.

Thanks for your help I got the naming the locations of the boundary sorted out.
