Hi

I am trying to use SU2 to simulate subsonic round jet flow. The case is from NASA TMR (https://turbmodels.larc.nasa.gov/jet...ichot_val.html). I use the 2D mesh and set Axisymmetric=YES. But the solver diverges. I cannot figure out the reason. It would be greatly appreciated if anybody can give me some guidance. The attached is cfg and mesh files.

Try lowering the CFL number and not using the CFL adaptation, it may help to converge

Actullay, I check your config file, and I do not know why there is a 'MARKER_FAR' BC, since in a nozzle, there should be no far field BC.
