[Archive] the user interface window freezes

Message by giovanni galgani:
I’m running a simulation in LEO orbit for a period of 2000 sec. The computation time is higher than the day. It often happens that the user interface window freezes. In these cases there is no way to awaken the application, therefore the result of the computation is lost because it is not possible to finalize the computation with the key ‘Extract date and save project’.
What are the causes?
I remark that the computational resources of the machine on which I make the simulation are more than enough in terms of RAM and CPU.

I may be wrong but a shorter period may be sufficient to get the potentials equilibrium well before 2000 s in LEO. Also, you have to pay attention to the time steps used in the different loops to speed your simulation and save CPU time (see the user manual).
