Hi,

Say I have modelled a simple Y-tube (consisting of one inlet and two outlets),I want to switch the boundary conditions between the two outlets to wall and outflow.I suppose this has to be done using CEL?
If so how do I do the switching?

You cannot do it in CEL. CEL (or CCL) cannot be used to change boundary condition types. You will have to run it through CFX-Pre again.

You have to load it in pre and change the BC type there, and re-generate the def file.
