By "crash" I meant "explode" not "DD is impossible." Explosions don't
happen because of parallelism, they happen because the steps are too large
for the size of the forces. The forces required to stably expand a box from
20A to 70A seem likely to be so large that I am very skeptical that you
could
If the job is not "very parallel", it will not crash.
It is better to preequilibrate in NVT beforehand. Cyclopropylchloride
is probably a liquid at 290K, if the model is parametrized reasonably.
So it should not phase-separate.

Really? Seems wildly unlikely to have occurre
Hello,
I am running a NPT simulation for cyclopropylchloride(1) in
50%water(100)+50%ethanol(100) using opls force field parameter .
After equilibration box size increases from 20 A to 70 A.
I used the following mdp file.

integrator = sd
