In most cases, this is related to solver steps beocming very small. Do you use a variable step solver?

OK, then the next step is to verify if the steps becoming very small is indeed the (first level) cause. Do you know how to find that out?

There are plenty of tool to debug and profile Simulink models. There is a bit of dependency by release. The question now is whether your project/learning justifies familiarizing with all of this. My suggestion is (I use R2014b) to use the "step forward" button and follow the time steps taken, e.g. by watching the overall simulation time in the status bar.

Amrutha, this was introduced in a recent release. But there are other ways. Point is: With this appoach, you will not be very quick in getting a solution. Look, 5 days are gone. I suggest that you look into the documentation and familiarize yourself with aspects of debugging and profiling.
