LMS Imagine.Lab AMESim is a simulation software for the modeling 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 it can be adequately described in a one-dimensional geometry representation. The sub-models in the system are linked using sub-model 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 of simulating 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 11 was released in 2011.CompanyThe 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, to control the raising of the Ekofisk North Sea petroleum platform), coupling hydraulic servo-actuators with finite-elements mechanical structures.
