Nonlinear iteration is not converging. Try reducing the minimum step size and/or relax the relative error tolerance.

I am facing difficulty when running my Simulink model. I always get the error message:
- Nonlinear iteration is not converging with step size reduced to hmin (4.11468e-032) at time 1.15818e-017. Try reducing the minimum step size and/or relax the relative error tolerance.
The time after which the programm crashes seems to change with certain constants in my model.
So far I have tried changing minimal step size, relative error tolerance, Number of consecutive minimum steps, absolute error tolerance, relative error tolerance.
Setings are variable step size and atomatic solver.
I am grateful for any help solving the issue.
Thanks!

The error comes up when one of the signals in your model is diverging to plus or minus infinity or changing too rapidly based on the solver settings.
