Run simulation by command

Hello Community,

is it possible to run a simulation by a command?

 

I would like to run two simulations of two different models.

The results of the first simulation are input values for the second.

 

Regards,

 

Nils

    Hello Nils,

    Short answer is: Yes you can.

    Let us consider that we have two Models: (A and B).

    If you want to share signals. A must create the signal using the SignalOut block and B will read the Signal using the SignalIn block.

    In that case the oml function will be

    function run_sims()
        vssRunSimulation('modelA',[],getcurrentenv);
        vssRunSimulation('modelB',[],getcurrentenv);
    end

     

    note the third argument is where the signal created by A is stored. In the example, it is the current environment, so you can directly access that signal, process it if needed before calling the second simulation.

     

    Hope this help.

     

    Thanks

    I have an additional question: vssRunSimulation ends when the simulation has finished? Or do the both simulations run in parallel?

    Thank you Fady,

    basically your solution is working. It worked several times...

     

    But after some time without any changes in the model this Error occoured:

    I had the same error with a 'toMat-file' Block and 'solved' the issue by deleting the block.

     

    @RoKet The Simulations run one after the other.

     

    Regards,
