Hey.
I have been performing simulations and validating results using SU2. I have successfully carried out 2D cases. However, I am having a hard time while doing 3D cases, as they are not converging.
Can someone help me by sharing an example of a 3D case config file dealing with Euler and Navier-Stokes equation?
Thank you.

There are some examples of 3D cases in the tutorials, as well as in the testcases repository. Those in the TestCases repository generally use a very small number of iterations, as they are for code regression testing purposes.

It is usual for 3D cases to be more difficult than 2D cases, and will take more iterations to converge. If you have not already tried, things like lowering the CFL number (if the residuals diverge) or raising the CFL number (if they are just converging slowly) and trying different limiters and numerical methods can often help.

Thank you. I did try that and it has converged. Much appreciated anyways.
I wonder if you could help me with paraview. How can I calculate Cp and do sensitivity analysis.

Try plot over intersection curves in ParaView for sectional extractions
