Hi,
I am running Incompressible RANS NACA0012 Tutorial.(https://su2code.github.io/tutorials/...ulent_NACA0012) Keeping all parameters exactly same except changing the Mesh file which is in cgns format(imported from ICEM CFD- The Mesh is QuadMesh with 84000 Elms). I found that Solution is diverging within 30 iterations. But if i use default .su2 file. Solution is running smoothly. Could anyone help me in solving the issue. Is it related to Mesh file.? I am attaching images of SU2 Error and picture of Mesh (Mesh file size is pretty big) |

Can you post the entire output of SU2, not just the residuals part.
The mesh quality statistics can indicate if there are conversion issues. |

That is almost impossible to read... Nevertheless, the maximum aspect ratio is very large (300000+) which can cause problems for the linear solvers, try reducing CFL a little maybe to 10-15 and if that does not work, reduce the aspect ratio of your cells.
You can also try 1st order (MUSCL_FLOW = NO) if the convergence is good that way you can go back to 2nd order but using a limiter. |
