Hi all,
I'm new to Ansys CFX and this is my first post so my apologies if this is in the wrong section or the question is too easy

I made a schematic drawing here: https://www.dropbox.com/s/czpkzrjoca...%20element.png

Black are the stationary wall's, red is a rotating wall (the outside of a rotating filter element in real life), green the outlet en yellow the inlet.
The internal volume I modeled with Solidworks and imported into Ansys Workbench. Creating a mesh I used all standard values and created some 'named sections'.
Then in the CFX-Pre window, I think I need to create 2 domains: 1 that is stationary and had the inlet and the black walls and the 2nd one that has the outlet and the red rotating walls. (Am I still correct?)

Now, when I make my first domain I chose as location B41 (or Assembly, but this is the same), but this is the total model. For the second domain I thus cannot select another location since "The same location has been specified for more than one domain."

Can anyone please tell me how I am able to 'split' my assembly so I can make 2 domains? And should that be done in the Geometry, mesh or setup window in Workbench?

I tried to find a CFX tutorial with multiple domains but all files were already meshed so I have no idea how this 'split' was done.

Kind Regard,
Martijn

It looks to me that you only have 1 domain. A domain would be a 3D volume. Your walls are boundaries, not domains. So in CFX-Pre you would insert boundary, apply it to the moving walls, and define the wall velocity.

I found it. Thank you

Hi everyone,

I am doing CFD analysis of centrifugal pumps using Ansys having volute as stationary part and impeller as rotating part. For meshing I m using ansys meshing but i don't know how to create interface between impeller and volute.
Please help
