Question

CREO CFD Analysis Boundary Conditions For an Assembly

Hello,

 

I have an assembly part that I am trying to do a flow analysis for. When I hit Create the Fluid Domain, it took over a day to create. After I selected my inlet and outlet surfaces for my boundary conditions. I then added it to my simulation. When I added it to the simulation, BC_1 and BC_2 were not created. This has happened to me before, but I don't understand why.

 

Does any have an idea for why this happens?

Does anyone know how to fix this error?

 

Any help would be greatly appreciated.

 

Also, does anyone know how to find different groups to post to? I have been having trouble with that too.

 

Thanks,

Greg Williams

You can add a boundary condition after the fluid domain is created. In your analysis tree, right click on the domain and select "add boundary condition". It should open a separate window with the domain and you can then select the surface(s) to use for the boundary conditions. I'm not sure off hand if you can do the inlet and outlet at the same time. If not, you'll have to do it twice.

When I do that, it doesn't allow to use those BCs in my analysis. I produces
another error.

My only other thought is that maybe it's related to your geometry. If it took that long to create the domain maybe you need to simplify the model. Are you comfortable posting a picture of it?
