Run in parallel a script and a real-time simulation

Hi everyone!

I will try to explain myself as clear as possible so that you can understand the problem I am facing right now, which maybe has been already solved, in which case I apologize.

I am running a Real-time Simulink Model (very simple one, a sine wave with a gain whose parameter is a variable, 'x1')

I want to change the 'x1' parameter from the gain block 'G1' during the simulation but the main problem I am encountering is that the simulation stops until the scripts ends and it is not simultaneous.

So my question is the following: Is it possible to run a script and a simulink model at the same time so that the variables from the script are fed into the simulink model as block parameters?

Thank you so much!

Kind regards,

Eduardo

Hi Eduardo,

As per my understanding, you are trying to update the parameter of the gain block using a script however the simulation stops before the script ends.

As a workaround, pause the mode, run the script and update the parameter and then continue the simulation. Alternatively SImulink function block can also be used to run the script.

Please find the documentations for more information:

I hope this helps!
