Atherosclerotic lesions preferentially develop in certain regions like bifurcations, branches, and bends [1, 2]. A possible explanation for such a preferential localization of atherosclerosis is that the geometry of the vessel influences the blood flow pattern. It suggests that the arterial geometry plays an important role in determining the localized blood flow information. Thus hemodynamic ...

Permanent magnets are ubiquitous in our world today, from refrigerator magnets to industrial sensor applications. Often, the magnitude of the field at a specific distance from an arbitrarily shaped magnet of variable strength is a necessary parameter for end-use systems. We used the the AC/DC module of the COMSOL Multiphysics® software to simulate field strength of permanent magnets for aiding ...

The modelling of a ferrite material is conventionally carried out using the Polder permeability tensor which assumes that the ferrite is saturated by a uniform magnetic field. This assumption is often inaccurate due to the constraints imposed by boundary conditions which renders the magnetic field non-uniform. This work proposes to overcome this by determining the magnetic field through a ...

The scope of this project was the creation of a short and comprehensive tutorial for the use of COMSOL® Application Builder for students at the University of Applied Sciences Bielefeld. The tutorial is based on the everyday life “problem” how to cool a beer bottle most efficiently. It shows how to use the most important features and tools (e.g. creating buttons, input fields, methods, generating ...

Ensuring the quality of underground water and controlling its quantity is of major concern for the population. Therefore, this subject attracts many students from different specialties at different levels of their curriculum. In fact, the pedagogic objectives of the course may be different according to the level or/and interest of the students and COMSOL is used due to its versatility. In this ...

This paper describes the use of COMSOL Multiphysics® to determine the shear layer thickness in thin–section aluminum extrusion, based on the minimum work criterion. The studied two aluminum alloys are AA 6063 and AA 7020. The results show that a continuous shear layer featuring shear localization due to localized thermal softening is not possible to form under typical thin&ndash ...

We will show how to carry out convergence studies of the FEM error on a sequence of progressively finer meshes in COMSOL Multiphysics on the example of Lagrange elements of varying polynomial degrees, which will also bring out the benefit of using higher order elements. The sample studies will focus on Lagrange elements of degree 1 through 5. For these elements, the convergence order of the ...

An experimental program has been developed, with the purpose of evaluating the reliability in building diagnosis and characterization of an integrated analysis of several parameters related to heat transfer process through the building material. The Infrared Thermography Technique (IRT) has been applied. Experimental measurements have been carried out on a concrete structure with an inside ...

The design of a right contour/structure of the NFC-antenna is presented. The NFC-reader-antenna is applied later to communicate with the NFC-tag (transponder) of a smart phone placed in the phone box of the car. The NFC-reader-antenna with selected contour is printed directly on the PCB and the antenna-PCB is placed under the phone box at the center console. The designed antenna must fulfill ...
