parallel computation with SU2 V3.2
 

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:

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

job aborted:

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,
