ztdep Senior Member p ding Join Date: Mar 2009 Posts: 427 Rep Power: 19	Dear friends: We consider a 2D square computation domain with a mass-sink(Q kg/s) located at the center position. I want to solve the flow fields and pressure field in the domain with the SIMPLE algorithm. But I am confused by how to set the boundary conditions on the 4 edges of the computational domain. Could you please give me some suggestions. Regards.
