revesed bullet simulation broken
 

Hello,

I am trying to get a simulation of a reversed bullet at subsonic speed. At the begining the simulation develops correctly but then the pressure increases and the speed decreases in the outlet. I have tested on different parameters in the outlet in both U and p (zerogradient, inletoutlet) but doesn´t work. What can I do? thanks.

File U

outlet_extruded
type inletOutlet;
inletValue $internalField;
value uniform (0 0 0);


In this link you can see the image and video of the problem
