COMSOL Multiphysics® Contribution to the Current Knowledge of the Proton Mass

M. Schuh [1],
[1] Max-Planck-Institut for Nuclear Physics, Heidelberg, Germany

Penning-trap mass spectrometers are the tools of choice for mass-ratio measurements of two different single ions with highest precision. The investigated ions are stored consecutively in a combination of an electric quadrupole potential and a homogeneous magnetic field at ultra-high ... Saiba Mais

Boundary Arbitrary Lagrangian-Eulerian and Deformable Boundary Perturbation Method

J. Rivero-Rodriguez [1], B. Scheid [1],
[1] Université Libre de Bruxelles, Brussels, Belgium

Partial differential equations on unknown domains is a mathematical problem that arises in many applications. Several examples can be easily found in the dynamics of free surfaces in fluid dynamics or in fluid-structure interactions. In many situations, large deformations are encountered ... Saiba Mais

A Pragmatic Multiphysics Numerical Model for Melt Hydrodynamics in Selective Laser Melting

Shashank Sharma [1], J. Ramkumar [1],
[1] Indian Institutes of Technology Kanpur, Kanpur, Uttar Pradesh, India

This study explores the significance of the recoil pressure, Marangoni convection and surface tension effects in selective laser melting of Ti-6Al-4V. A pragmatic two dimensional model with appropriate powder distribution over a substrate of finite thickness has been developed in COMSOL ... Saiba Mais

Controlling the Deposition Regime in Close-Proximity Spatial Atomic Layer Deposition with COMSOL®

When applied to live cells, SECM ... Saiba Mais

Simulating Survival and Insulin Secretion in Pancreatic Islet Tissue Constructs

E. Han [1], L. E. Niklason [1],
[1] Department of Biomedical Engineering, Yale University, New Haven, CT, USA

Type I diabetes results from the autoimmune destruction of pancreatic islets and is a growing and cost intensive chronic health problem throughout the world. Monitoring blood sugar levels and recurrent intervention with exogenous insulin allows many patients to lead relatively normal ... Saiba Mais

Optimizing Elastomeric Mechanical Cell Stretching Device

A-J. Mäki [1], J. Kreutzer [1], P. Kallio [1],
[1] BioMediTech Institute and Faculty of Biomedical Sciences and Engineering, Tampere University of Technology, Tampere, Finland

Cell morphology, orientation, and fate of differentiated stem cells can be affected by mechanical stimulation. Mechanobiological studies help to understand the molecular mechanisms of cells sensing and responding to mechanical cues. Previously, we have developed a vacuum-operated ... Saiba Mais
