LMS Imagine.Lab AMESim is a simulation software for the modelling and analysis of one-dimensional (1D) systems. The software package offers a 1D simulation suite to model and analyze multi-domain, intelligent systems and to predict their multi-disciplinary performance. Model components are described using validated analytical models that represent the system’s actual hydraulic, pneumatic, electric or mechanical behavior.
To create a simulation model for a system, a set of validated libraries can be used, containing pre-defined components for different physical domains. The user can compose a physics-based model of a system, provided this can be adequately described in a one-dimensional geometry representation. The sub-models in the system have to be linked — for this purpose each sub-model has ports, which can have several inputs and outputs. Causality is enforced by linking the inputs of one submodel to the outputs of another submodel (and vice-versa). This approach gives the capability to simulate the behavior of intelligent systems before detailed CAD geometry becomes available.
The system runs on most UNIX platforms (particularly under Linux) and on Windows.
LMS Imagine.Lab AMESim Revision 10[1] has been released in November 2010.

The AMESim software was developed by the Imagine Company, which was acquired in June 2007 by LMS International. The Imagine Company was created in 1987 by Michel Lebrun to control complex dynamic systems (initially, control of raising the Ekofisk North Sea petroleum platform), coupling hydraulic servo-actuators with finite-elements mechanical structures.
LMS is a software and engineering services provider for companies in the automotive,[2] aerospace and other advanced manufacturing industries. LMS International delivers a combination of virtual simulation software, testing systems, and engineering services. Their focus is on the mission-critical performance attributes in manufacturing industries — including structural integrity, handling, safety, reliability, comfort and sound quality.
The LMS headquarters are in Leuven, Belgium. LMS is a spin-off from the K.U. Leuven in 1980.[3]
In its use, LMS Imagine.Lab AMESim is quite similar to Simulink. A major difference is, that within LMS Imagine.Lab AMESim the variables, shared at the ports between submodels, are physical and operate in both directions. MathWorks recently introduced an add-on series of physical modeling tools to Simulink in which connections between blocks are bidirectional and similarly represent physical connections.
LMS Imagine.Lab AMESim is a multi-domain software. This means that it allows to link between different physics domains (hydraulic, pneumatic, mechanic, electrical, thermal, electromechanical). It is based on the Bond graph theory.
The modelling of a system is done in four steps:
Between the submodel and parameter mode, the AMESim model is compiled. Therefore it is necessary to have a compiler. Under the Windows platform, LMS Imagine.Lab AMESim works with the free Gcc compiler , which is provided with the software. But it also works with the Microsoft Visual C++ compiler.
Since the version 4.3.0 AMESim uses the Intel compiler on all platforms.
LMS Imagine.Lab AMESim offers a wide range of features that make it a complete platform for modeling and simulation:
LMS Imagine.Lab AMESim is provided with two default libraries: mechanical and signal. The other libraries (approximately 30) must be purchased separately.
To create a system simulation model in AMESim, a large set of validated libraries can be used for pre-defined components from different physical domains. The large set of libraries eliminates the need for extensive code writing and it enables development teams to make complex system models that cover multiple physical domains. In this way, these libraries accelerate model creation and free up time to optimize designs. LMS says the library components are all completely validated.[4] This contributes to the accuracy and the reliability of simulation results.
LMS Imagine.Lab AMESim offers libraries for:
LMS Imagine.Lab AMESim-Suite is constitued of different applications:
LMS Imagine.Lab AMESim is used by major OEMs and suppliers in the automotive, aerospace and mechanical industries worldwide. The reference list includes companies like General Motors, Toyota, Renault, PSA Peugeot Citroën, Bosch, Continental, Delphi, Airbus, Embraer, Dassault, Snecma, Caterpillar, Komatsu, Cognizant and CNH Global.[5]
LMS Imagine.Lab AMESim is used worldwide by many engineering schools and universities. It is also the reference framework for various Research projects in Europe.
