Dear all,

All examples works well, but gridRefinement2d didn’t works. Anyone know how to fix?

mpirun noticed that process rank 0 with PID 22514 on node pinoquio exited on signal 11 (Segmentation fault).

2 total processes killed (some possibly by mpirun during cleanup)

Dear Josepedro,

to execute the code you need to give the resolution as a command-line argument. So, to execute with, say 4 processes and resolution N = 50, you need:

mpiexec -np 4 ./dipole 50

An appropriate diagnostic message has been added to this example, and it will be included in the next Palabos release.

Best,
Dimitris
