Hello,
I got a segmentation fault using decomposePar. Usually, decomposePar works fine but in this case I receive Code:

Hi Jutta,
You might try using the latest 2.1.x version to see if any bug has been fixed since your 2.1.0 build. If that still fails, you could post your mesh here, and/or submit a bug report to opencfd. Kevin |
