Hi ,everyone,I can compute the file "inv_ONERAM6_JST.cfg" in parallel in "TestCasesv3.2.0\TestCasesv3.2.0\euler\oneram6 ",my computer is win 7 64 bit,the su2 is V3.2,but when I compute the file "inv_NACA0012.cfg" in "TestCasesv3.2.0\TestCasesv3.2.0\euler\naca001 2",I face some errors,and I can not fix it,the error is showing:
------------------------------ Begin Solver -----------------------------

!!! Error: NaNs detected in solution. Now exiting... !!!

job aborted:
[ranks] message

[0] application aborted
aborting MPI_COMM_WORLD, error 1, comm rank 0

[1] application aborted

C:\SU2\SU2_CFD aborted the job. abort code 1

raise Exception , message
Exception: Path = D:\,

SU2 process returned error '1'


when I compute the file "turb_ONERAM6.cfg" in parallel,the error is SU2_CFD stop working,and is showing:
------------------------------ Begin Solver -----------------------------

job aborted:
[ranks] message

[0] terminated

[1] process exited without calling finalize

---- error analysis -----

C:\SU2\SU2_CFD ended prematurely and may have crashed. exit code 3

---- error analysis -----
SU2 process was terminated by signal '3'
CSysSolve::modGramSchmidt: w[i+1] = NaN
CSysSolve::modGramSchmidt: w[i+1] = NaN

these errors are troubling me,I look forward to your rely.Thank your rely.

Hi,

The solution has gone unstable. Please choose less aggressive settings in the config file (lower CFL, no multigrid, etc.) until you find a stable configuration, and then ramp up in order to improve performance.

Hope this helps,
Tom
