    Simulating vacuum at a boundary

    Vikram Manthri

      I have a tube ( smaller dia) in a system through which vacuum pump is pulling the air . Also air is being blown from outer nozzle (bigger dia).  I have specified the side to which vacuum pump is attched as static pressure BC.  My model ends at the pipe. Is that BC right as immediately after the boundary you have air which is at atmospheric pressure ?
