ISMuS : An information system to support the development of digital simulation models for multibody systems motivation, requirements and concept

The National Aerospace Laboratory NLR In the Netherlands develops simulation systems that are used by industry to evaluate product designs by means of digital simulation studies. Such systems Involve simulation models and simulation tools. The simulation models are software representations of the product that is to be evaluated. As such, the...

Development environment for digital simulation models of multibody systems

Requirements are formulated for an environment for development, verification and validation of digital simulation models of multibody systems. A realization of such an environment at the National Aerospace Laboratory NLR is described.

Simulation of partitioned dynamical systems

In this report some aspects of the analytical and numerical solution of Partitioned Dynamical Systems (PDSs) are discussed. A PDS is solved using the Lagrange multiplier approach. The resulting equations are combined to obtain Differential-Algebraic Equations, describing a PDS. The additional algebraic equation leads to error accumulation when a...
