Massive Parallelization of Multibody System Simulation

Acta Polytechnica, 2012
This paper deals with the decrease in CPU time necessary for simulating multibody systems by massive parallelization. The direct dynamics of multibody systems has to be solved by a system of linear algebraic equations.

Leveraging 3d‐4f Coordination: Molecular Quantum Spring‐Magnet Behavior in Axial Ni2Ln Complexes

Angewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
We report heterotrimetallic Ni2Ln complexes mimicking exchange spring magnets at the molecular level. CASSCF calculations show collinear anisotropy axes, while µSQUID studies reveal slow relaxation and open hysteresis in Ni2Tb, Ni2Dy, and Ni2Ho. Ferromagnetic 3d–4f coupling and anisotropy alignment enhance bistability, offering promise for quantum, and

Effect of tibial tray backside design on stress transfer and micromotion in uncemented posterior‐stabilized TKA: A finite element study

Journal of Experimental Orthopaedics, Volume 13, Issue 1, January 2026.
Abstract Purpose The uncemented posterior‐stabilized total knee arthroplasty (PS‐TKA) gained increasing acceptance as younger and active patients have higher requirements for the lifespan and functionality of prostheses, because their frequent gait and deep‐flexion activities may amplify tibial implant–bone interface micromotion and increase the risk ...

Multibody Dynamics Model of a Human Hand for Haptics Interaction [PDF]

, 2008
In this paper we propose a strategy for modelling a human hand for Haptics interaction. The strategy consists in a parallel computing architecture that calculates the dynamics of a hand; this is accomplished by computing the dynamics of each finger in a ...

Symbolic Computations in Multibody Systems [PDF]

, 1994
Symbolic formula manipulation has proven to be an efficient tool in the dynamical analysis of multibody systems. A multibody system data base is introduced and its implementation using a CAD-3D-software is shown. Starting from the data base the equations of motion are generated by a coordinate partitioning approach combined with the projection ...
