Multilayer planar transformers are widely implemented in power electronic applications. The design process of these elements is complicated due to the complexity of a magnetic circuit and high frequency interactions between windings. Additionally, an analytical approach to the analysis (based on mathematical formulas) can be uncertain. The applied FEM method of the analysis can be a solution to ...

In the core of Chemical Engineering is the reactor design that includes most of all scientific disciplines. The reactors, in general, are treated ideally. Unfortunately, it is observed in the real world a very different behavior from that expected. Thus, to characterize nonideal reactors is used, among others, residence time distribution function E(t). The aim of this present work is to ...

This paper presents information on techniques needed in COMSOL Multiphysics® to enable computational studies of coupled systems of PDEs for time-dependent non-linear problems. Furthermore, we demonstrate how to use data files as input for initial conditions. To illustrate the techniques, we consider a system of two time-dependent non-linear PDEs from mathematical biology that couples an ...

This report mainly discusses the implementation and results of a project proposal, “Modelling using Finite Element Methods”. The report is devoted to implementation, which is a model of an electromagnet. The software tool that is used to model the electromagnet is COMSOL Multiphysics®, a commercial FEA package provided by the University of Manchester, Computer Science School. Additionally, the ...

Geometries with heterogeneous material properties are typically defined as a set of multiple parts, each part representing a different material. However, assembling or defining the individual parts of complex geometries can be difficult. A practical method based on image-based mesh generation, a custom algorithm for labeling materials, and interpolation functions of COMSOL Multiphysics® can be ...

This paper is focused on topology optimization of heat transfer and fluid flow systems for multiphysics objectives. Specifically, COMSOL Multiphysics software is coupled with a method of moving asymptotes optimizer in a custom COMSOL / MATLAB script. Various physical process including conduction, convection-diffusion, and Navier-Stokes flow are considered. To illustrate the method, a standard ...

The paper presents a method of extraction of electrical equivalent circuit of a one port surface acoustic wave (SAW) resonator from the results of simulation based on finite element method (FEM) using COMSOL Multiphysics software. A one port SAW resonator consists of large number of periodic interdigital transducer (IDT) electrodes fabricated on the surface of a piezoelectric substrate. A ...

Morphogenesis is a tightly regulated process that has been studied for decades. Previously we developed data-based mechanistic models for a range of developmental processes with a view to integrate the available knowledge and to better understand the underlying regulatory logic. In our previous papers on simulating organogenesis in COMSOL Multiphysics® we discussed methods to efficiently solve ...

COMSOL Multiphysics was used to design a binocular load cell. A three-dimensional linear solid model of the load cell spring element was studied to quantify the high-strain regions under loading conditions. The load cell was fabricated from 6061 aluminum, and general purpose Constantin alloy strain gages were installed at the four high-strain regions of the spring element. The four gages were ...
