CFD Analysis Creation of Boundary Conditions

[GWW.2]

Hello,

Currently I am trying to run a CREO Flow Analysis for my parts and I am having trouble making boundary conditions for my inlet and outlet for the parts I have created. 

When I did the Without Heat Transfer: Power Inverter Overview tutorial on CREO, I was able to do it flawlessly. Now when I do the tutorial,  I automatically get BC_1 and BC_2. When I do CREO flow simulation for my parts, I don't get the those boundary conditions at all and when I try to add them, it doesn't allow me and the error I get says "Selected surfaces don't refer to single fluid domain" even though I have created my fluid domain. 

I have the two images attached to this post. Let me know what I can do to fix the problem.

Thanks,

Greg

Hi if you got that error, it may due to the solid is not added to the simulation as simultion domain, please try adding domains first then create BC patches.
