TheStudent New Member SZ Join Date: Mar 2017 Posts: 3 Rep Power: 9	I want to setup a Film cooling over a flat plate with a row of holes in Fluent. When i set the Bc i wanted to use the pressure far field as a Bc. I let the input on the farfield on default and only got divergence, but when i only change the pressure far field to symmetry, it completely convergent. What is the big difference between those two bcs?
