Why am I receiving error message about singularities in my Simulink model!!!

Hi ; i am receiving the following error message about singularities in my Simulink model: " | Derivative input 1 of 'EXEMPLE1/MADA courant /Subsystem3/Integrator' at time 0.01 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).|" ny suggestions in this regard? How can I fix it? thanks in advance
