Setting velocity gradient as BC at opening
 

Hi! I've been trying to figure out how to impose velocity gradients (obtained from DNS) as my BC at an opening, instead of cartesian velocity components. Is it possible to do that? If yes, anybody knows how?Do I have to write a User Fortran routine? Thanks

I specify the veloccity gradients as velocity components. I wonder is theres any other way.

I'll try that, thanx.

If there is another way, I haven't found it yet...
