Default Time depend velocity inlet and outflow
Posts: n/a

My problem is follow:

Have a time depend simulation where the velocity inlet and the outflows are depends the time (have the time functions). But I don't know how set these.

I'm happy, if have the sample file

Hi, Seizopha

You can impose the time-depend boundary condition by UDF. There is a similar example in FLUENT 6.1 UDF Manual, refer to below chapters.

6.7 Time-Dependent Macros 11.1 Boundary Conditions
