In this paper, a two dimensional finite element based microstructural model is constructed using Voronoi tessellation for representing polycrystalline material. Elastic wave propagation and Heat diffusion studies are then performed on constructed microstructure model.Computational issues ... En savoir plus

A COMSOL Multiphysics®-based Model for Simulation of Methane-Hydrate Dissociation by Injection of Superheated Carbon Dioxide

M. Gharasoo[1], C. Deusner[1], N. Bigalke[1], M. Haeckel[1]
[1]Department of Marine Geosystems, GEOMAR - Helmholtz Centre for Ocean Research, Kiel, Germany

Immense amounts of methane are stored as gas-hydrate deposits in deep layers of marine sediments. This has raised considerable interest to develop strategies for producing natural gas from marine hydrates. One potential production strategy is the injection of supercritical CO2 into ...

COMSOL Multiphysics® Simulations of Cracking in Point Loaded Masonry with Randomly Distributed Material Properties

A.T. Vermeltfoort[1], A.W.M. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

This paper describes COMSOL Multiphysics® simulations of the stress and crack development in the area where a masonry wall supports a floor. In these simulations one of the main material properties of calcium silicate, its E-value, was assigned randomly to the finite elements of the ... En savoir plus

Bloch Waves in an Infinite, Periodically-perforated Sheet

W. Maysenhölder[1]
[1]Fraunhofer Institute for Building Physics, Stuttgart, Germany

Bloch waves in infinite periodic structures – much in vogue in the present metamaterial age – can be conveniently studied by COMSOL Multiphysics® software. This is demonstrated by a simple, yet rich two-dimensional example: a perforated sheet with square symmetry. Instead of plane waves ... En savoir plus
