I tried using different pressure velocity coupling schemes. It is not converging for SIMPLE, SIMPLEC and PISO. When I use coupled it is working well. I used SIMPLE for all of my previous simulations and I would rather not change my method. Do you have any idea why coupled is converging while all the other are not converging in this case?
I tried using the k-e-turbulence model and it is converging as well.
