No, absolutely not. I said decrease maxCo to 1. if you have conv. errors, attach the conv. curve here.

modify nNonOrthogonalCorrectors to 1 or 2 only if you have problems with the pressure residuals. this correction may help, but not too much as I experienced. It increases the calculation time as...

did you try cellLimited Gauss Linear 1?

cellLimitation helped you to have better convergence. leastSquares is slower than linear in my opinion.

Hi,

I could use Co numbers up to 1. At the beginning of the simulation the max Co increases a lot, so the solver decreases the timestep. Later, the timestep as well as the meanCo increases. At the...

The procedure is the same for me except I'm using ICEM CFD and exporting to FLUENT V6. I think you are just simply lucky with your mesh.

Can you give me the mesh sizes on the interfaces? Whats...

Hi Foamers,

have you tried AMI rotating things using unstructured tetrahedral mesh? In my case I have to use it due to the complexity of my geometry, but I have convergence problems (blowing up...
