How to solve the simulation error ,try reducing the minimum step size and/or relax the relative error tolerance.

HI,

I am working on a hexacopter model and i am getting the following error

An error occurred while running the simulation and the simulation was terminated

Caused by:

• Solver encountered an error while simulating model 'FullHexacopterwithoutpositionandwithwindmodel12thapril' at time 5.0198902479053622 and cannot continue. Please check the model for errors.
• Nonlinear iteration is not converging with step size reduced to hmin (1.78342e-14) at time 5.01989. Try reducing the minimum step size and/or relax the relative error tolerance.

Component:Simulink | Category:Block diagram error
