I'm modelling an engine system in Simulink. To avoid skipping a specific crank angle, I'd like to simulate the Simulink model in the "crank angle - domain" with the following configuration parameters (for example): Start angle: 0° Stop angle: 360° Step size: 0.01°

How can I switch from the default time-domain (Start time, Stop time, etc.) to the described "crank angle - domain"?

I don't know if it works, but you can try by parametrizing the time step and the simulation time in function of the engine speed, but I believe it works only with constant engine speeds.
