I want to know how do I implement free boundary condition on the cuboids. On the far end of the cuboid, the surface opposite to the nozzle (not attached to the nozzle), i have given pressure outlet. What should be my gauge pressure here to simulate at atmospheric conditions? Last edited by anuroopak; July 20, 2012 at 20:20.
