2D Compressible Nozzle

Hello,

I cant seem to get convergence for a compressible 2d jet, I am getting the following error "time step continuity errors :" I have checked and double checked the boundary conditions and I cant see whats wrong I have tried varying the B.C's but no good. I am using rhoSimpleFoam. I would really appreciate the help how i can fix this thanks !!

Hi, skumar!

The "error" here doesn't mean "wrong", but is similar to "deviation", it measures the deviation of the CFD program to the conservation laws.
