Something strange happend, when I tried to run this rather big case (10^6 cells).

The solver just quit with the message "killed" after the first timestep.

When running in paralle I got this additional message:

mpirun noticed that job rank 1 with PID 5466 on node M1530 exited on signal 15 (Terminated).
1 process killed (possibly by Open MPI)

Whats that?

No problems in time-stepping on my machine. 2GB of memory. The solver uses up to 900MB and including OS-uses it goes to 1200MB.

If you remember, I'm using a virtual environment to run my linux system.
I just doubled the the amount of memory and now it's working.
