Simulink vs GT Suite

[durablack2]

I am wondering the differences in capabilities between Simulink and GT Suite in terms of automotive simulation as well as the main use of each program. I know there are a number of different simulation programs out there but I am specifically interested in these two. My understanding is that Simulink is more for simulating controls whereas GT Suite is more for modeling complete system performance. Any thoughts / input much appreciated.

GT suite is mostly used for engines, Simulink is used for anything.

Exactly what Greg said. GT-Suite and Simulink actually can be used quite well together.
Both solve nonlinear DE's that model physical systems.
You can essentially do the same with both. But, for example if you want to simulate the entire thermal system of an engine, you are better off starting with GT and run some experiments to tune system parameters. In SL you will have to to much more modeling and the effort will be 2 or even 5 fold.

Thanks guys. That's kind of what I had in mind. I've done a bit more research and it seems that when using both together for automotive simulations, it is common to implement MATLAb solver functions into a Simulink model for optimizing component sizing / best fit and then add a "Simulink Harness" into GT power that will allow the GT Power model and Simulink model to be used in conjunction with one another. The engine components are simply modeled in GT Power where as the control parameters are more easily modeled in Simulink (i.e. injector control, egr, etc.)

Exactly.
