Hi everyone,


i am trying to simulate a fan. A rotating fluid domain is defined on location impeller. Frame type of this domain is rotating as well. I want to have velocity on the walls as zero and that is why i specified them as counter rotating wall. But after starting simulation I got an error that mesh on the wall is rotating.


1-What should i do to remove this error and let the simulation run?


2-Do you have any other suggestions except my way above not to have velocity on walls?



Thanks in advance for your help!

1) You mention: I want to have velocity on the walls as zero
On which walls do you specify counter rotating wall.
2) what error do you get exactly. Can you share your output file?

3) Also, please add a picture. That can explain more than 1000 words
