Hi
I run the simulation on MPI.

first, i make
constraints=all bond  => successful

second, i make
constraints=none  => segmentation fault

is the "segmentation fault" coming from the NONE bond-contraints?



The rest of your parameters and whatever is in your system is not stable in the absence of constraints. There is probably plenty of information in your .log file or screen output to use as material to search the archive and diagnose the issue. Also see the wiki page about "blowing up."
