Hi,

I am trying to make an executable file out of my Simulink model using Real Time Workshop. My model is configured to use Variable-step solver and converting it to Fixed will change the dynamics. How can I use Real Time Workshop with Variable-step Solver?

Thanks

Hi
I'm not exactly sure, but on the surface, that looks to me that there
is no way to do that for most targets. The whole point in real time is
to execute your algorithm within a finite, fixed interval, to get an
output definitely at every sample time. If your algorithm is not
assured to finish in that time (which is what you are effectively
saying when you want a variable time steps), you are saying that you
might not get an output at every sample time, which defeats the
purpose of real-time.
