I have two questions.
1. I am used to using the maximum number of steps as the stop standard. Is there a way to set the time as the stop standard? 2. When using the maximum number of steps as the stop standard, I set the X-axis of the monitoring drawing curve to physical time, but why is there no change in the monitoring drawing at runtime? A curve appears when you set the X-axis to the number of running steps. |

1. Go to stopping criteria and change it to physical time
2. I don't know what you're doing wrong but it has nothing to do with stopping criteria. I've made plots with physical time on the x-axis. Maybe check out a tutorial or something. |

Hi, I went to the tutorial and found this sentence:
If you are running steady state solver, but want to use physical time for drawing, run the unsteady state solver first, then switch to the steady state solver. This ensures that there is a "physical time" in the simulation. I'm doing steady state analysis, but I don't understand exactly what to do with this sentence. |

There is no physical time in a steady simulation so you cannot have time on the x axis of your monitor plots, only iteration number.

If you are running a steady state simulation, why are we even talking about physical time?
