Create a virtual Surface into a domain in CFX PRE
 

Hi everybody,

I need to create a virtual surface in CFX PRE and i don't find how to do it.

In fact, I would like to do it in order to calculate for each step(for a transient simulation) an average pressure using the following CEL expression:

areaAve(p)@Surface

The problem is that my surface is not a boundary condition or an interface, but it is located inside the domain.

Does that possible?

Thanks a lot
