Dear CFX user,

Do anyone know, how to give non-uniform boundary conditions (say heat flux) in a plane surface of a 3D objects? in ANSYS CFX

My heat flux value is not uniform, so i want to give this value like this. Maximum at the center and minimum at the edges (NORMAL DISTRIBUTION).

Can ANYONE give idea for my problem.


Regards,
SENcfx

This is easily done with a CEL expression. This can be an analytical function or a 1D/3D interpolation function.

The problem is probably associated with a complicated GGI linking the solid and fluid domains. Check your interface mesh is well resolved and of good quality.
