Back to the origin<\/strong><\/h3>\n\n\n\n

Michel Lebrun was a university teacher when he founded the company Imagine S.A. in 1986. Meanwhile, he was giving courses about the bond graph theory<\/strong> during summer university, gathering a wide community of experts to exchange about that engineering approach.<\/p>\n\n\n\n

To put it simply, the bond graph<\/a> is an explicit graphical representation showing dynamic variables, that reflect energy transfers between systems. It\u2019s a powerful modeling tool for engineers and is a structured approach to modeling and multidisciplinary systems simulation.<\/p>\n\n\n\n

This practical approach enables to model and understand the energy transfer between the inner components of the system, as well as the energy storage, dissipation and modulation leading to the dynamics of the system, whatever the underlying physics.<\/p>\n\n\n\n

That\u2019s by getting associated with Pr Claude W. Richards, in April 1994, who was programmer working on a solver at Bath University that the adventure started. Michel Lebrun brought the physics and bond graph knowledges while Claude W. Richards brought the solver.<\/p>\n\n\n\n

Where does this name come from? \u201cAmesim\u201d stands for Advanced Modeling Environment for SIMulation. <\/em> <\/p><\/blockquote><\/figure>\n\n\n\n

This partnership led to the first commercial release of AMESim in 1995<\/strong>. This first version was dedicated to fluid control systems and hydraulic topics, with a first and unique HCD (Hydraulic component design) library called AMEBel (basic element library).<\/p>\n\n\n\n

Indeed, the first application of this AMEBel library was for Sandvik company (formerly Tamrock), for the design of hydraulic hammers. Customers such as Bosch or Peugeot-Citro\u00ebn followed, some of whom still use Simcenter Amesim today.<\/p>\n\n\n\n

The graphical interface and the modularity provided by the software brought significant improvement to the hydraulic system modeling time, switching from 1 week to 10 minutes!<\/strong> <\/p>\n\n\n\n

From pink to grey<\/strong><\/h3>\n\n\n\n

Some of our engineers, who were there from the beginning, have seen many\nchanges over the years! <\/p>\n\n\n\n

The evolution is not only in the functionalities, with the first Windows version, the drag and drop use, the library tree, the contextual window, the Undo\/Redo function, etc. But also, behind the scene, with the separation between GUI pieces of code and algorithmic ones, the splitting of code into smaller and better-defined modules, and so on until today. <\/p>\n\n\n\n
