Stop and start from the last time step

Hello sir,

I want to stop a running simulation and start it after a while from the latest time step? Is that possible ?

Best regards.

Hi Ali,
Yes, you can do that. But you also need to plan for this in advance.
This means, when you run your first simulation, use the P 40 and P41/ P42 options. This saves a state file in intervals specified by the commands above.

In order to continue the simulation, include I 40 /I 41 options. The simulation will load the previous state file selected using I 41 and continue from that point.

Be aware that files that print time series will be overwritten, so take care to save them separately before hot starting the second simulation.

Hello Sir,

I met a problem when I want to restart a simulation from the previous state file.

I have included P40 and P41, so I have state files, but when I include I40 and I41, then restart the case, the step and simtime are not right as shown in pictures attached. Could you please help about this?

Regards.
