Two differents BC in the same surface
 

Hi all.

I'm simulating flow in a pipe with heat transfer. At the pipe wall I need to specified heat flux just for first quater of total lenght and wall temperature for the rest. My problem is that I can't set two different kinds of BC at the same surface. Can I do something to do that in CFX-Pre? or Do I have to compose the wall for two different surface and then meshing?

Thanks

Miguel

You should create two separate 2D regions for the wall in CAD before meshing.
