slow simulation because of integrator

Hi! My simulink system could not simulate all values, so simulink provided a link so all values could be simulated in the integrator, but now the system is simulated very slowly because of the integrator. How can I get simulink to simulate normally again.

Hi @Magda

Since no details are provided to describe why the simulation is slow, I can only guess that the system is stiff. To address this issue, either remove the stiffness or use a stiff ODE solver.

Hi Sam! Okay will try, but do you know if there are any possibility to reverse that link i clicked on?

Hi @Magda

Could you specify the link that you clicked?

You can also find examples of solving stiff systems at this link:
