AMESim
Encyclopedia
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 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.
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. This contributes to the accuracy and the reliability of simulation results.
LMS Imagine.Lab AMESim offers libraries for:

The modelling of a system is done in four steps:

- submodel mode: in which the physical submodel associated to each component are chosen,
- parameter mode: in which the parameters for each submodel are chosen,
- run mode: in which the simulation is started.
