This paper presents a parallel formulation for efficient multibody dynamics simulations with many degrees of freedom. The proposed method adopts a divide and conquer scheme and is formulated by using augmented Lagrangian formulation. The algorithm can accommodate situations, in which the Jacobian matrix is rank deficient, which may occur in analysing complex systems with redundant constraints and...
The aim of our study was to determine the influence of microirrigation and organic fertilization on the vitality of white birch (Betula pendula Roth) seedlings and the occurrence of soil mites (Acari) after edaphon inoculation. Nursery experiments were carried out in 2003-05. It was found that the studied factors influenced seedling vigour, soil properties and the occurrence of mites.
Parallel computers are becoming more available. The natural way to improve computational efficiency of multibody simulations seems to be parallel processing. Within this work we are trying to estimate the efficiency of parallel computations performed using one of the commercial multibody solver. First, the short theoretical outline is presented to give the overview of modeling issues in multibody...
