I am getting the following error while solving. Can any one suggest the solution..

Derivative of state '1' in block 'mgpid/Transfer Fcn2' at time 2.456895 is not finite. The simulation will be stopped. 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)

Thanks in advance.

Hi Shambhu, could you share the model and data for use to help you further. This error simply means the denominator part is getting to zero some of your input values, you can either analyze and find out the data or reduce the step-size or use variable-step size for solver.
