orthogonal cutting

Hello everybody,

i try to perform a 2D orthogonal cutting simulation using the Johnson-Cook damage model in ABAQUS/Explicit. When simulated on my desktop PC (AMD Phenom quad core processor, Windows Vista 64bit), the simulation runs successfully. But if I try to run the simulation on a linux cluster, it ends with error messages related to HP-MPI. Moreover, if I run a 3D drilling simulation on the cluster, it runs successfully with no errors.

I use ABAQUS 6.7.5, CPE4R elements.

Example of error messages from *.log file:
