Good evening,
I am trying to carry out a calculation of a centrifugal fan but the calculation doesn't converge (graph in attachment) : Do you have any idea of what could be the root cause ? Thank you in advance. Best regards, |

Ok, I think I found the issue.
0 pressure at inlet seems to cause the problem. Solved if I put 0 at outlet and zero gradient at inlet. |
