SU2 Min and Max coodinates

I am trying to solve for a flow in a converging nozzle, but I keep getting an error stating: FGMRES orthogonalization failed, linear solver diverged.

I have also noticed after analysing the output from SU2 that it has detected the following:

Wetted area = 0 m.
Area projection in the x-plane = 0 m, y-plane = 0 m.
Max. coordinate in the x-direction = -1e+010 m, y-direction = -1e+010 m.
Min. coordinate in the x-direction = 1e+010 m, y-direction = 1e+010 m.

The detected minimum and maximum coordinates are not consistent with the actual values. Also the area values are 0. I have tried using the same mesh (different format) on Fluent and it runs fine. I am only getting the diverging problem on SU2. Any ideas?

Assuming you are exporting the grid in CGNS format, change the CGNS options (ADF / HDF) I am not sure which one we support, but there are not that many options.
