The paper presents a multi-index variable time step method for the integration of the equations of motion of constrained multibody systems in descriptor form. The basis of the method is the augmented Lagrangian formulation with projections in index-3 and index-1. The method takes advantage of the be

β¦ Synopsis
The paper describes the implementation on a transputer system of a novel parallel algorithm for dynamics simulation of a multibody chain. The algorithm is formulated at a level of parallelism which is natural for the problem but is essentially unavailable to other simulation dynamics algorithms. The experimental results demonstrate that one can improve efficiency of computation by exploiting this level of parallelism. However, analysis of the performance shows that the serial component of the resulting parallel algorithm grows to be a large fraction of the total parallel execution time and therefore limits the speedup that can be achieved with this appro a c h .

Monte Carlo and finite element methods are numerical techniques used for solving complex problems in reactor physics and radiation shielding. In this paper we are concerned with the implementation of existing research-level codes based on these two methods, written originally for serial computers, o
## Abstract The simple cubicβlattice model of polymer chains was used to study the dynamic properties of adsorbed, branched polymers. The model starβbranched chains consisted of __f__β=β3 arms of equal lengths. The chain was modeled with excluded volume, that is, in good solvent conditions. The onl
A new finite element beam formulation for modelling flexible multibody systems undergoing large rigidbody motion and large deflections is developed. In this formulation, the motion of the 'nodes' is referred to a global inertial reference frame. Only Cartesian position co-ordinates are used as degre
This article describes the collisional dynamics (CD) method adapted for molecules with geometrical constraints within a description using Cartesian coordinates for the atoms. In the CD method, stochastic collisions with virtual particles are included in usual molecular dynamics simulations to couple
