Ok, the problem is that you make the -solve and -pos steps together.
Then the solutions at each time step are kept in memory, so that you
will sooner or later fill all the available memory on your computer!

To avoid this problem, simply perform

- first the -solve step. The memory used by GetDP will be constant
during all the process (after the first time step is completed). The
solutions are saved in the '.res' file after each time step (or
depending on your 'SaveFct[]').

- then re-run GetDP with the -pos command. It will simply read the
'.res' file, and perform the post-processing only on the saved
solutions.
