Residuals of continuity not converging

Well, I'm solving a case like "flow over a cylinder". The residuals of continuity is not converging. Maybe there's not a steady state solution for this case. But I want to know the pressure drop. So how about performing a unsteady case?
I wonder if I can get a precise answer. Thank you. Last edited by hjxy2012; August 26, 2016 at 03:45. |

Hello ,
send a picture of your mesh here to see if it is a mesh problem or not. |

The mesh is posted here. I didn't use inflations to keep the number of elements within a reasonable range. Thank you. |

Well, I set a monitor of inlet pressure and change the solution method from simple to coupled and the result is more stable.
