I'm simulating a flow in a T-junction. So for the inlet flow at a branch I have to add an oscillation with the velocity. I'm fairly new to FLUENT.

The oscillation function is as follows:


How would I go about creating a UDF to implement that?

You need to do some of the basics tutorials on UDF's to get a fee for it.

Try this one:

Then, the only difference with yours is that you will need to get the "time" every instance you call the UDF. You can do that with...

real t_glob = RP_Get_Real("flow-time");

Good Luck!
