Hi
I have an airfoil mesh, and its overall boudary is set to velocity inlet. I want to run a compressible flow analysis, so i changed the boundary to pressure-far-field (in fluent). i tried to run the compressible problem based on the fluent tutorial (tut.3 from ansys) and inputted the same commands. But the iterations fail, with the message "amg solver error". Does anyone know how i can solve this problem? i have tried changing some of the solution conditions but i am getting very inaccurate resluts. thanks! |

1. Check mesh
2. Try changing the solver 3. Try relaxing URFs |

check mesh for errors
do case check before iterating |
