Hello Everyone!

I posted this question earlier but got no replies, so I am posting this again in hopes of getting some help or insights. I have a rectangular pipe, with an inlet on one side and an outlet on the other side, higher pressure on the inlet and lower pressure on the outlet, so the fluid should flow from the inlet to the outlet.

The solver I wanna use is rhoSimpleFoam. I got some really good results with sonicFoam but I want to use a steady-state solver. Right now I am getting some reasonable profiles but the solution diverges soon, chiefly because I think I am not setting up the relaxation factors in fvSolution correctly.

Kindly look at my case and tell me what I could be possibly doing wrong. This is a test case and should be very easy to figure out (ironically). Please please help.
