Default 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

Hi,

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.
