Hi,

 Derivative input 2 of 'Single_wheelset_susp_mass/Lateral wheelset_inertia /Integrator2' at time
0.012988383999014474 is Inf or NaN.  Stopping simulation.  There may be a singularity in the solution.  If not,try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances).

I get this error when I run the Simulink model. It seems a divide block in the model performs a divide by zero operation. I have worked on it for a long time still not able to solve this issue. I have even looked into the below link for help, but I still couldn't make it.

Thanks
