Default Loss coefficient at openings

Hello,

I am using CFX5.7 to model natural ventilation in a theatre. I am using 'opening' as the boundary condition at both air inflow area(low level) and outflow area(high level). The solver works ok without setting any loss coefficient. But after I set the loss coefficients at 'opening' (for example, 2.69) I always have the linear overflow problem. Any suggestion about this problem? Thanks a lot.

Regards, Forrest
