shangzung Member Dennis Rown Join Date: Oct 2009 Posts: 51 Rep Power: 17	Hello! I am using sonicFoam to simulate pressurization inside a tube. But until now I could not find out what are good fitting BCs for U, p and T to reflect pressure (walls) and to let through pressure (holes). Does someone have an idea what BCs make this simulate right?
