Dear all, how to define the external airflow boundary conditions, expecially for the outlet? since there is more than one free face? I set the velocity inlet as the inlet boundary condition. outflow as the outlet b.c.? How about the other free face? Could I give them pressure outlet? Could I mix use the pressure outlet and outflow in one case?

Thanks in advance

Use the far-field bc on all your external bc. Luca

sorry, I did not mention that it is incompressible flow. therefore, the far field could not be used
