The problem is that the summit only allows me to run the simulation for two hours with a number of 42 nodes. So the simulation stops every 2 hours and then I have to restart from the latest time with startFrom: latestTime. Restarting from the lates time every 2 hours has brought me convergence problems. I check this, running a simulation without stop and running the same simulation but with stop and restart. Is there a way to fix this problem? perhaps smoothing the start of the simulation?
