Hi!

I didn't use udfs before but in this problem i have to use so i need help. Transient.

There is a pressure inlet which should opened at time 2sec. I need a udf for this situation.

Waiting for help..

Hi Gulyuz,

I think the best way for you is this:
1. Look in the Fluent manual for a UDF that does something similar, i.e. a time-dependent boundary condition.
2. Try to change the UDF so that it matches your needs.
3. If you don't succeed, post your attempt here, and we can help.
