boundary conditions for separation in distillation column
 

Hi all,

I'm trying to simulate a 2D distillation column. I generated the mesh via blockMesh, however, to run the simulation, I'm so confused about how to insert bc. I have three inlets (feed, reflux, from reboiler), and three outlets (top, bottom, to reboiler), and I have parametric values obtained from Aspen HYSYS, however as I'm new on OPEN FOAM, I get errors when I try to specify them. Can anybody offer me any source that I can read in this matter?

Thanks.
