hello everyone;
Recently I have been testing the limitation of the range of mach number and complex cases. And I found something wrong with the newest version.
When I use 0012 airfoil to test the limitation of mach number , I found over ma5 the solver will exit with error just as following:

Error in "void CSysSolve<ScalarType>::ModGramSchmidt(int, std::vector<std::vector<ScalarType> >&, std::vector<CSysVector<ScalarType> >&) const [with ScalarType = double]":
-------------------------------------------------------------------------
FGMRES orthogonalization failed, linear solver diverged.
------------------------------ Error Exit -------------------------------

I changed my configure for several time and could only change the step number where it stopped. So I wonder if the error came from my wrong settings or I have reached the limitation of the code now.

I would be appreciated for any help, thank you for your reading.

Best wishes;
