Ansys Insight: Did my simulation stop before the auto shutoff minimum was reached?

      When you run a simulation in FDTD the job manager window shows the auto shutoff level, which is a measure of the energy left in the simulation window. This value is used to determine if the calculation can be stopped before the end of the simulation time. In some cases it might happen that the job manager shows the value of the auto shutoff to be 1 or some value smaller than 1 but larger than the minimum from the simulation settings (1e-5 by default) and then the simulation suddenly stops. This does not necessarily mean that the simulation did not reach the condition for early shutoff. If the log file created during the simulation shows the following message:

      Early termination of simulation, the autoshutoff criteria are satisfied.
