Solve non linear system equation with simulink

Hi, i'm Gaia. I want to know if is it possible to solve non-linear system equation using Simulink and how can i do. Thank you!

Can you share your equation?

The equation of motion of a vehicle

Yes it can be, by using regular Simulink blocks(Mathematical blocks). Try something, show some effort and then come back with specific questions.

I've already tried, but I have problems with integrator because it says that there is a critical point... I try to reduce step size, change solver but nothing! So I linearize the system thinking problems are in the non linear system, but always the same
