if you rae using FLUENT can you convert to ploy and try may be you can avoiad this
Mesh-ployhydrel-convert domain or smooth and swap |

Is there a method where i can change my Y axis to X axis. So that i dont have to make it again? Even if it is possible in workbench please let me know? |

As far as I know, there's no necessity for 3d geometry to define x axis as axisymmetric B.C. Good luck |
need help
Hello my name is aan. Now I'm doing project about combustion zone in secondary reformer of ammonia plant. Can anyone check mesh generated in my project? I really appreciate if there is someone who would like to discuss with me.
Best regards, AAN |
Good day
I have a problem when I am simulate unsteady flow around a propeller, divergence detected in amg solver. x momentum, I reduce the URF but is the same problem |
Its probably an issue with your boundary conditions and/or mesh then. Double check your BCs, refine your mesh and put the URFs back to the defaults. The default URFs with make your solution converge quicker.

try changing the mesh and relaxation factor

I got a similar problem now. I added a udf velocity profile at the inlet of a pipe and the domain is only quarter of real geometry with periodic boundary condition. I have tried all the ways that mentioned above but the error message still comes out every time "Divergence detected in AMG solver". Could you tell me that how did you solve your problem with the periodic bcs? Thanks Chris |

It must be done in pre processing
