nisha New Member Nisha Join Date: Sep 2009 Location: Massachusetts Posts: 18 Rep Power: 17	Could anybody help me how to write a udf for streamfunction for given u,v data ? I KNOW that streamfunction contours can be directly viewed from post-processing facility in FLUENT, but my problem is related to development of functions similar to streamfunction from u,v data. streamfunction $\psi$ is defined as, u= d $\psi$ / dy, v=- d $\psi$ /dx A simple udf for streamfunction should help me getting started. Thanks a lot..!
