Hi Vishnu,
I see that you have met with an algebraic loop in your Simulink Model.
To eliminate this message, you can do the following: Configuration Parameters(Ctrl+E) --> Diagnostics --> Algebraic Loop --> choose noe from the drop-down.
However, as the error message points out, it is not a good practice to have Algebraic Loops in your model.
Therefore I suggest you to go through the following solution by MathWorks Support Team:
This solution gives a clear understanding of Algebraic loops, and it also sheds light on resolving them with better practices for modelling.
