Cylindrical refinement zones

[tmoser]

Dose anyone know of a way to make a hollow cylindrical refinement zone? What I'm after is a zone that looks looks a tube instead of a solid bar. I currently have a cylindrical refinement zone but if I try to create another zone I get a fatal error and CFA crashes. The documentation says you can set up any number of refinement zones.

Hi

CFA supports multiple refinement zones. Could you share your project if that is possible. i can take a look. thx. For hollow cylindrical one, you can use expression to define it, just 3 lines of code, could you contact your support for how to do that.
