Models are described using nonlinear time-dependent analytical equations that represent the system's hydraulic, pneumatic, thermal, electric or mechanical behavior.

This portfolio is intended for development of complex products that include smart systems, through implementing a Predictive Engineering Analytics approach.

The Imagine S.A. company was created in 1987 by Dr Michel Lebrun from the University Claude Bernard in France, to control complex dynamic systems coupling hydraulic servo-actuators with finite-elements mechanical structures.

In the early 1990s the association with Pr C. W. Richards,[3][4] coming from the University of Bath in England, led to the first commercial release of Simcenter Amesim in 1995 which was then dedicated to fluid control systems.

[12][13][14] Simcenter Amesim is a multi-domain software that supports modeling a variety of physics domains (hydraulic, pneumatic, mechanic, electrical, thermal, electromechanical).
