Hi, I'm trying to impose some boundary conditions for the velocity, pressure and temperature. The geometry is easy: unit square.


I'd like to impose something like x^4+xy^4 on a patch. How can I do ?

Yes, I found it. I used the function SetExprBoundaryFields with the file SetExprBoundaryFieldsDict
