Pressure Drop at a Plane
 
Hello, I am trying to model a complicated test rig geometry which will have a turbine in it. I do not want to model the turbine explicitly, but I wish to include the pressure drop it will induce in my analysis. It appears to me that the way to do this (according to CFX manual) is to define a subdomain in which I can set either a source or treat it as a porous media. However, surely it is much simpler to set a pressure drop at a defined plane as one can do in both Tascflow and Fluent. Does anyone know how to do this?

Re: Pressure Drop at a Plane
 
There is no option for a planar resistance, it has to be a volume (one of the long time deficiencies of CFX-4 and CFX-5). You can create a very thin region and create a subdomain on it with the proper resistance.
