Hi again, I realized that the pulse generator was causing the problem. When I replaced the generator with a manual switch, everything worked well. What am I doing wrong please? I connected the generator to a mux since it is a shared event. I set the period to 2sec with 50% cycle. What is causing this please?

The bit about Continuous States was never a problem. It was a note telling you that you were working with a discrete time system instead of a continuous time system. ode solvers are only useful for continuous time systems. I imagine that continuous time could have been forced by selecting a different kind of signal, but I am not familiar with how those operate.

The only bit I was concerned about was the part about some of the states being only conditionally reachable, leading to potential instability. And that appears to have been solved.
