hello every one, i got an error in simulation during running. please help me out how can i rectifies that error, it is a closed loop . the error is as shown in the BODY

Simulink cannot solve the algebraic loop containing 'overmodhighLPHASE1/Subsystem5/Relational Operator1' at time 0.0 using the LineSearch-based algorithm due to one of the following reasons: the model is ill-defined i.e., the system equations do not have a solution; or the nonlinear equation solver failed to converge due to numerical issues. To rule out solver convergence as the cause of this error, either a) switch to TrustRegion-based algorithm using set_param('overmodhighLPHASE1','AlgebraicLoopSolver','TrustRegion') b) reducing the ode45 solver RelTol parameter so that the solver takes smaller time steps. If the error persists in spite of the above changes, then the model is likely ill-defined and requires modification.

It explains what an Algebraic Loop is and how you can resolve it.
