what do this outputed results indicate us?
 
in the paraview picture there are some high pressure and low pressure points that should not be there.also in the outside of entrance.what does those mean?(I know this type of bad results may have a name i can't remember.whats that?)
is mesh bad?or schemes?
I have used a huge reservoir with a tiny tube attached to it with lower pressure than it as initial condition.
