Top 10 analyses to run with Simcenter Amesim engine models and how to choose the most suitable one
Thanks to its long history and expertise in the engine modeling area, Simcenter Amesim allows to model an internal combustion engine in many different ways, depending on the goals ...
We are used to talk about the scalability of Simcenter Amesim, but it goes way beyond this single word and we could say that the only purpose of this capability is to satisfy user’s needs.
Indeed, there are so many needs when it comes to engine modeling, and so many ways to model an engine in Simcenter Amesim, that without guidance, the user could choose an inappropriate submodel with the associated unwanted effects.
Here is a non-exhaustive list of the numerous ways a 4-cylinders engine model can be modeled, which user’s needs it satisfies and some hints about which one to choose based on several relative criterion.
