Innovative Meshing Strategies for Bearing Lubrication Simulations

Adaptive Tetrahedral Meshing for Personalized Cardiac Simulations

Personalized simulation for therapy planning in the clinical routine requires fast and accurate computations. Finite-element (FE) simulations belong to the most commonly used approaches. Based on medical images the geometry of the patient’s anatomy must be faithfully represented and discretized in a way to find a reasonable compromise between accuracy and speed. This can be achieved by adapting...

Multigrid Solution Strategies for Adaptive Meshing Problems

This paper discusses the issues which arise when combining multigrid strategies with adaptive meshing techniques for solving steady-state problems on unstructured meshes. A basic strategy is described, and demonstrated by solving several inviscid and viscous ow cases. Potential ine ciencies in this basic strategy are exposed, and various alternate approaches are discussed, some of which are dem...

The True Cost of Bearing Lubrication

Lubrication corrections for lattice-Boltzmann simulations of particle suspensions.

The lattice-Boltzmann method has been refined to take account of near-contact interactions between spherical particles. First, we describe a comprehensive solution to the technical problems that arise when two discretized surfaces come into contact. Second, we describe how to incorporate lubrication forces and torques into lattice-Boltzmann simulations, and test our method by calculating the fo...

Innovative Strategies for Tissue Engineering

Unmet need. It is beyond dispute that human population is ageing. For the first time in history, people age 65 and over will outnumber children under age 5. This trend is emerging around the globe, and will bring several challenges for health technologies. For instance, in a few decades, the loss of health and life worldwide will be greater from chronic diseases than from infectious diseases an...
