Variable wall velocity
Hi, I have a query. In fluent, there is an option for moving boundary but the velocity should be constant. Is there anyway to assign variable velocity through an UDF? Thanks

Re: Variable wall velocity
could you describe more what you really want to do ?

Re: Variable wall velocity

Thank you for your response. See, Fluent has a provision to assign either linear or angular velocity to the wall/boundary. But this velocity should be a constant not a function of time. But I need to specify the velocity as a function of time. Say, I want to simulate a vibrating wall whose velocity varies sinusoidally. How can I approach this problem? If you can throw some light on this, I would be thankful to you.

Warm regards,

R. Sambasivam.
