I am simulating airflow among several rooms, what BC should I set for a door between two rooms? I know I do not need to set any BC for the internal door. But I set the door BC anyway to make an easy calculation in Post.

Should I use an opening, static pressure=0,turbulence option: low (1%)?

Thanks in advance.

Thank. But I tried opening,inlet and outlet, none of them worked in CFX 5.7 for an internal door (CFX-Pre complained). After I deleted it, everything is fine.

you cannot have a boundary (like opening, or inlet) inside the domain!

If you want to monitor the variables or mass fluxes, you have to do it without the boundary conditions.

Thanks. However, it would be nice if CFX allows such a "boundary" just for postprocessing purpose.
