Continuation of simulation from previous runs

Continuation of simulation from previous runs

Feb-12-14 08:55:59

I have a model that successfully ran from   startTime=0 to endTime=10 say ... and the results are saved in    OldResult.mat
Now I want to rerun the model starting with results   at  T=5,   and continue to run it for another 10 seconds from that initial condition and the new results saved in a different output file.

How can this be done?

I also want to do the same.
Maybe for the past 8 years there are a way to do this?

Maybe Equation System Initialization File (Optional): and Equation System Initialization Time (Optional): on Simulation flags tab is a solution?

You can use "Equation System Initialization File" and Initialization Method "none" to restart simulation with some values from a result-file to chain simulations.

But if you use an external state (external functions, external objects), delay functions, spatialDistribution or perhaps if you use a lot of events and need to preserve pre-values/etc, you might get some unexpected results.
