Hi,
I was analysing dynamic simulation results and I've noticed that every step
of the dynamic starts with a high temperature (more or less 400 K).
Consequently also the plot of the potential energy presents a very high
fluctuation.
These are the parameters I'm using for the dynamic and the plot resulted by
the simulation.

Is it a big deal to start a simulation with a temperature higher than the
boiling point of water?
I'm attaching here one of the steps of the dynamic
Thank you in advance
