Hello, I'm working with a stenosis model showing blood flow across the stenosis with a set velocity. I wish to make the velocity time variable (ex:in a sin wave form or something), and I understand I need to write a short program for that. I have no idea how to do that. Can somebody help please??

PS. pretty please?

I think you need to use the DEFINE_PROFILE and write an UDF. The UDF manual has a very detailed example on how to write this UDF and hook it to your simulation.

thanks! I'll try that.
