Hi,
Thanks for your guidance. Is there any documentation regarding the comparison between the Simulink modelling(with basic equations) and Simhydraulics modelling?
Are there any papers published in this regard.

Regards,
Jithendra Dharmavaram

Not that I know of. It's probably because you can model quite complex systems in SimHydraulics, which would be very difficult and cumbersome (if at all feasible) to do in Simulink from first principles. For example, the laminar-turbulent transition is automatically taken care of in SimHydraulics, whereas you would need to implement this for each component you model from first principles. You would propably also have a lot of numerical issues with algebraic loops, etc... So it's probably only doable to compare the two on very simple examples, which doesn't do SimHydraulics justice, and which is probably why the sort of comparison you are after isn't available.
