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.

Thanks for reply. I am hereby attaching a file.. which is having complete output of SU2.

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.
