Hi all

I am attempting to simulate flow over a submnarine at a constant speed.

I am using ANSYS CFX, k omega or SST turbulence model, A structured mesh with icem.

When I have coarse mesh it solves and RMS residual converges however when I have fne mesh RMS residual will not converge and there is fluctuation in RMS.

Can anyone offer some advice from previous expeience?
