Yes, this is not unexpected. DEN is very time consuming, and is often measured in days, not minutes or hours.

If you still see a load on your processor, then it is probably still running.

Do you have access to a machine with multiple processors? Doing a full optimization on a single processor is going to take a very long time.

Hi,
I launched a DEN refinement 4 hours ago, and it remain stuck with the
following message:

----------coordinate minimization before annealing----------

Running DEN torsion optimization on 1 processors...
Running torsion simulated annealing
...trying gamma 0.0, weight 3.0

Is this normal? Is torsion simulated annealing so long?

Thanks,
