I'm having a problem that I've never experienced before. For some reason I'm struggling with continuity not converging. It's not diverging, but it's also not solving fully. I am toying with my solution schemes but cannot find a good mix of schemes. Most of my solution is being solved using QUICK, but currently my pressure is solved using the SIMPLE solver while my Pressure-Velocity coupling uses SIMPLEC with a skewness correction of 1.
Previously I've had one of my grids converge using a second-order pressure scheme and PISO with skewness correction for the p-v-coupling, but all subsequent grids have diverged with this method.
I'm waiting in queue to run another simulation using SIMPLE as my p-v-coupling solver too but it may be a while.
Are there any thoughts on how to get continuity to converge?
