Hi, I am having some trouble with the compressible flow solver when I run the attached case.

I am attaching the .xml file and the .out file

This is the error I am getting and don't know how to solve it:

Warning : Level 0 assertion violation
# Nonlinear solver not converge in DoImplicitSolve

Primary job terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.

mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

Process name: [[52564,1],2]
Exit code: 1

Any Help or comment will be extremely appreciated.
