Hello everyone,

I am writing here to receive your help.
I am simulating sour sediment over the cylinder. The simulation with a cylinder at 90 degrees is good. However, when I change the cylinder with 80,70,...30 degrees, the solution does not correct and it said that "pressure iteration did not converge in itmax= 100 iterations". After that, the solution is stopped.
I changed the value at multiplier for dynamically adjusted convergence criterion which in pressure solver options>>convergence controls to 100 and 10^6, but that situation continuously occurs.
Please help me explain and solve this problem.
Thank you in advance.

Hi Mai Loan,

Try to improve your mesh. Use nested block or confirming mesh. Refer the manual for more information.
