amirhosseintaran Member Amirhossein Taran Join Date: Sep 2016 Location: Dublin, Ireland Posts: 57 Rep Power: 10	Dear foamers, since I've been searching too long for this issue, I'm starting a new thread in this regard. the main question is " how we set the P $_{0}$ in a DSMC case? " do we have any developed B.C library for this? I'm trying to simulate a case of supersonic flow with Ma=6, here I need to introduce the P $_{0}$ in order to get the coefficient of pressure but there is a huge difference in the order of magnitude between the P $_{0}$ in the paper and my results, P $_{0}$ in the paper was set at 5 bar and the pressure which I obtained from the solution is about 1e-05 bar !!! please share your ideas if it's possible. Regards, Amir
