switching boundary conditions between wall and outflow

moniker · February 9, 2012, 01:46

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.

can you elaborate when you say ,you have to run it through CFX-pre again?say I designed the tube ,setup the mesh and defined already existing boundary conditions in setup ...Being a novice and a first timer I cant help but ask you again

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