Hi everyone,
I am having complex tubular structure which is designed in Solid works. Then, I have used 'Volume Extraction' option in Space-claim to generate the fluid domain. I have done meshing in ANSYS. To solve CFD on the same, while importing fluid domain with mesh in CFX, it is automatically creating default interfaces, which is acting as wall , and not allowed me to flow fluid (since my fluid domain is completely solid, please correct me if I am wrong).
So, Is there any option through which I can delete all those interfaces ?
Or Should I make fluid domain which contains only surfaces having only two interface 1) inlet face 2) outlet face.

Thank you.

Regards,
Sanket

In CFX-Pre you can just delete the default interfaces. They will then become walls by default, so you have to define them as something. Or you can turn detection of the default interfaces off and the default interfaces will not be generated at all.

But this is caused by the way you are solid modelling this. You might be able to eliminate the interfaces entirely by making sure the blocks are joined together correctly. Alternately carefully placed interfaces might make meshing much easier. So it depends on exactly what you are doing.
