Hi, CFX users

I am trying to set boundary conditions of 'exponential or parabolic velocity distribution' at pipe inlet. How can I set the BC's. Thanks.

hi Kim,

If you are using an "inlet" boundary condition you can specify the inflow velocity condition node by node using the user fortran subroutine, USRBCS.
