We demonstrate cartogram construction, where a geographical map is distorted to represent some measure, for example population, while trying to keep the shape of regions recognizable. We then apply this cartogram construction technique to optimize thermocouple locations. A heat generation and conduction model is used initialize the cartogram construction algorithm. A uniform distribution of ...

Laser thermal treatment (LTT) systems have applications in IC fabrication for improving low-k dielectrics properties, polymer curing and resist processing. This contribution deals with a transient model of fast scanning and pulsing laser multi-beam system used in semiconductor processing. General Heat Transfer application mode formulation with multi-scale modelling approaches are employed. The ...

During the past decade reverse engineering has become a common and acceptable practice utilized by many aftermarket suppliers, and even original equipment manufacturers (OEM). This presentation focuses on the applications of multiphysics software such as COMSOL and Simpleware® in reinventing the design details and manufacturing processes of an existing part in the absence of the original design ...

Zur Vorkonditionierung der nichtlinearen Magnetfeld-Fem-Gleichung nutzt man das Biot-Savart Gesetz. Durch eine Integration über Randströme lässt sich hier die Vernetzung des Freiraums umgehen. Aufgrund der Konvexität der Energie-Funktion des Problems bietet sich eine nichtlineare Variante der „conjugate-gradient“-Methode als einfaches Lösungs-Verfahren an.

Single photon emission computed tomography (SPECT) is a nuclear medicine imaging technique that uses gamma rays. It has been especially useful for bone scans, cardiac perfusion imaging, tumor scans and brain imaging. The main advantage of SPECT imaging is that it can target particular tissue receptors allowing one to focus on the imaging of the diseased tissue. In most cases Monte Carlo ...

The capillary network is a complex-interconnected structure. A single blood cell traveling from the arteriole to a venule via a capillary bed passes through, on average, 40−100 capillary segments. The cardiovascular systems responsible of delivering blood to the tissue under sufficient pressure to exchange materials. This is a two way process, at which nutrients, Oxygen, and other ...

Computers are used every day to efficiently perform mathematical computations. For engineers to work efficiently, abstraction is necessary; this means hiding lower-level details of an algorithm to emphasize higher-level structure. In this presentation, the fluid exploration with CFD is explored. The presentation is based on a course held at Woodruff School of Mechanical Engineering.

Identifying molecules requires associating molecular structures with their electronic energy levels. In this paper we introduce a novel technique for the calculation of molecular Rydberg levels. The technique allows for easy visualization of the associated wavefuntions to make unambiguous assignments. The value calculated for the 3p state of trimethylamine is most closely in agreement with recent ...
ComsolGrid – A Framework For Performing Large-Scale Parameter Studies Using COMSOL Multiphysics and Berkeley Open Infrastructure for Network Computing (BOINC)

BOINC (Berkeley Open Infrastructure for Network Computing) is an open-source framework for solving large-scale and complex computational problems by means of public resource computing (PRC). In contrast to massive parallel computing, PRC applications are distributed onto a large number of heterogeneous client computers connected by the Internet where each computer is assigned an individual task ...

Using modeling software such as COMSOL Multiphysics during the design phase, an approach called “simulation-led design”, allows ideas to be both inspired and validated by the use of simulations. Then, using simulations after the product is designed can shorten the prototype-testing portion of the development process and reduce its cost. This paper provides specifics on the nature of the ...
