Simple pipe
 

Hello
I'm want to simulate an air flow thru a pipe.. So i have a pipe loaded as complement the "inlet" to this pipe is loaded as a hole. Next BC inflow is set by a pressure p=1.03e3. I m using physics gravity, viscus... Voind initial state is set to p=0.5e3. When i run simulation a dont get any results.. Does anyone done something like that. I know this is very simple but i cant handle it:(
