I have a simulation with an environmental pressure inlet with a surface area of 61.8 sq.ft. (7.415" x 100 ft long). After running the simulation, I'm seeing results with a surface plot showing an inlet velocity of ~5 ft/s, when it should actually be closer to 10 ft/s. Also, the surface parameter shows an area of 123.6 sq.ft., which is twice what it should show. So, Flow Simulation is interpreting that surface to be twice as large as it really is, and the velocity is half as a result. Any ideas what could cause this??
