adding the missing atoms seems to give another problem.
The original simulation runs fine for a very long time.
cp2k.psmp equil.inp > equil.out
However, restart the simulation with the same file gives
cp2k.psmp test.inp > test.out
Translating the system in order to center the QM fragment in the QM box.
