Alla har vi väl velat bli osynliga vid ett eller annat tillfälle. Som Dagens Nyheter och Ny Teknik nyligen rapporterade om har vi på COMSOL dragit vårt strå till stacken. Forskare använder COMSOL Multiphysics för att simulera och designa avancerade metamaterial. Redan idag finns det högeffektiva antenner och i framtiden går det kanske att skapa akustiska mantlar, båtskrov med lägre vattenmotstånd eller osynlighetsmantlar. Det lär nog dröja ett tag innan en hel människa försvinner in i mörkret bakom en osynlighetsmantel (man kan tyvärr inte se ut bakom en verklig sådan). I väntan på det har vi gjort en liten video som förklarar.
The LiveLink™ for SpaceClaim® interface allows you to transfer a 3D geometry CAD model from SpaceClaim® to COMSOL Multiphysics. Updates to the model will synchronize seemlessly between SpaceClaim® and COMSOL Multiphysics. This brings you the fusion of direct modeling with multiphysics simulation in a tightly integrated environment, enabling optimal designs and collaboration across CAD and CAE teams.
COMSOL provides everything needed to define and build meshes and FEA/CFD style problems, but also something more fundamental. COMSOL also allows problems to be defined from fundamental physics. Al Dean reviews version 4 in this Develop3D Article.
The latest issue of Building Simulation, Volume 4, Number 1 / March 2011 , reports on how multiphysics modeling and simulation is being applied to develop and design buildings. Titled “Special issue: Multiphysics Modeling and Its Application in Buildings” this journal features seven papers spanning a variety of application areas. In each paper COMSOL Multiphysics is being used to model the complex processes encountered in building simulation. The Journal is available online and is published by Tsinghua University Press, co-published with Springer-Verlag GmbH.
COMSOL Multiphysics offers direct access to mathematical models utilized in its interfaces and allows users to customize their own theoretical model within COMSOL with unparalleled ease. Here are three video tutorials on how users can add their own Partial Differential Equations (PDEs) within the COMSOL Multiphysics interface.
Ed Ethridge of NASA who used COMSOL Multiphysics in his discovery of water on the moon will be a guest speaker for the upcoming webinar Thursday February 10th, 2011 at 2pm EST. During the webinar Ed will present part of his research on cryogenic trapped water just under the surface of lunar soil at the Moon’s poles. He will discuss how microwave energy can be used to efficiently extract this water from permafrost and how COMSOL permitted the calculation of the extraction process.
Electromagnetic Simulation in COMSOL covers current, fields, and waves. Brief examples include joule heating in a fuse, coupled physics and total inductance in inductors, and electromagnetic waves in a 90 degree h band waveguide.
