Simulink cannot solve the algebraic loop containing 'untitled_​with_error​/Ship dynamics/Add1' at time 0.0 using the LineSearch-based algorithm due to one of the following reasons...

I have designed a simulink model in order to simulate ship motion and maneuvering by modeling the dyamics of the system. I am trying to find a solution to this problem for a long time but yet nothing that it can help me. I have tried the suggestions of simulink provided from the Diagnostic viewer. Also I tried to use unit delay blocks or algebraic constaint block but without sucess (Maybe I do not put them at the right point). I really need help if someone knows to answer. I would appreciate it a lot. If anyone needs more information to provide in terms of my simulink model, let me know.
