Hi guys
when I design for a nonlinear model in simulink a pid controller, and I want to run the simulink, it gives me bellow image.
(max step size is 0.2s , please go to configuration parameter and set "automatic solver parametric selection" to "none". although, I do that again it gives me this warning and when I see the scop, it does not give me a good result, it gives me just 0 in output instead of giving 2 things( output and input).
I attach also my slx file.

It is my understanding that you are having some difficulty in choosing a solver for your model.
The automatic solver recommends a fixed or variable step solver based on your maximum step size. If you’re not satisfied with the results from the auto solver, I suggest manually choosing the solver and comparing the different results with the tradeoffs. For example, decreasing the step size in a fixed-step solver will increase the accuracy of the results but increases the time required to simulate the system.
