Pro/e to cfx geometry filler

Jmac · May 30, 2011, 23:23

Hi all,
I am undertaking a cfd analysis of a fairly complex shower mixer component. I have a CAD model of the component itself in pro/engineer but what I require is a model of the internal cavities (where the fluid is flowing through) that can be used for a cfd analysis. Due to the complexity of the part it is not possible to create this from scratch in design modeller or otherwise. Is there a feature on ANSYS or pro/engineer that I can use to create the cfd geometry?
Any help would be appreciated,
thanks

In ANSYS Meshing, you would want to extract a flow volume... It basically does a boolean subtraction.

In ICEM CFD, you would just place a material point inside and close the inlets and outlets... ICEM CFD is a surface based modeler and doesn't need to do a boolean, you just say which volumes you want meshed...

If you can be more specific about which tool you are using, we can give more specific instructions.

I'm using pro/engineer to transfer to ANSYS CFX

No, I meant what meshing tool are you using...?

If the answer is ANSYS Meshing, then you could do a flow volume extraction...
