refine ur grid or use PRESTO option for pressure interpolation.

thanks for the help. i tried changing pressure cycle to FLEXIBLE and it has helped and the case does not diverge. but the continuity residuals keeps fluctuating. is it alright if the residulas keep fluctuatuing between 1e-4 and 1e-5.
thanx for the advise |
