SU2_DDC error with version 2.0.5
 
Hello

I was trying to partition the onera M6 wing mesh (given in euler testcase
directory) using SU2_DDC of SU2 v 2.0.5.
I mentioned no. of partitions in the .cfg file.
However it doesn't partition the mesh and exits without doing anything.

Also, on some linux system, the earlier SU2_DDC versions ( 2.0.4) shows the error
*** buffer overflow detected ***: /home/diwakar/su2/SU2v2.0/bin/SU2_DDC terminated
when the number of partitions mentioned in the .cfg file exceeds 99.

Can anyone tell how to resolve these issues ?

Thanks

In the current developer's version of SU2 the number of processors in SU2_DDC is specified via command line e.g. mpirun -n 12 SU2_DDF default.cfg

The grid partitioning and writing is done in parallel, and it looks like that for your particular application you need to increase the number of cores.

Cheers,
Francisco
