Hi everyone, I am dealing with a nonNewtonian laminar flow that I solve through a customized Pimple solver (as more equation are required). I have recently noticed that if I stop the simulation and then I restart from the latest time step the results will considerably change with respect to the ones obtained not stopping the simulation.

I am stopping the simulation in a forced way (I know it is not optimal, but I always make sure through the log that the "latest" folder has been written completely). After that, when I restart from "latestTime" everything starts changing, reaching after a couple of seconds a completely different state.

I am using the adaptive time step, but after I restart, the time step value is the same of the unarrested one.

Do you have any suggestion about this? Did it ever occur to you?
