Analysis of a Three-phase Transformer Using COMSOL Multiphysics and a Virtual Reality Environment
The simulation software COMSOL Multiphysics is applied to the numerical com-putation of the magnetic fields of a three-phase transformer. A three-dimensional model of the geometrical configuration is created with the help of the CAD tools of COMSOL Multiphysics. There, all dimensions of ... 詳細を見る
Design and Optimization of a High Performance Ultrasound Imaging Probe Through FEM and KLM Model
The present paper describes the development of a full FEM model for linear array high performance 5MHz ultrasound imaging transducer. As a preliminary design, a mono dimensional electro-acoustical KLM model was realized, then the complete FEM was developed and optimized. The optimized ... 詳細を見る
Semismooth Newton Method for Gradient Constrained Minimization Problem
We treat a gradient constrained minimization problem which has applications in mechanics and superconductivity. A particular case of this problem is the elastoplastic torsion problem. In order to solve the problem we developed an algorithm in an infinite dimensional space framework ... 詳細を見る
Solving the Paraxial Wave Equation using COMSOL
Here we present and discuss numerical solutions to the paraxial wave equation using COMSOL (2D, PDE, General Form, time-dependent analysis). Ultimately, the goal is to extend this treatment of free-space beam propagation to the case of propagation through a medium that is non-uniform ... 詳細を見る
Dynamic Simulation of Bone Morphogenetic Protein Patterning in a 3D Finite-Element Model of the Danio Rerio Embryo
Zebrafish development of the dorsoventral axis relies on the spatiotemporal distribution of Bone Morphogenetic Protein (BMP) signaling, which is regulated by numerous secreted molecules such as Tolloid, Sizzled, and Chordin. The rich dorsal/ventral patterning network must achieve both ... 詳細を見る
Boundary Element Technique in Petroleum Reservoir Simulation
Petroleum reservoir simulation is a process of modeling the complex physical phenomena inside a reservoir. This study presents an application of an analytical based numerical scheme so called the Boundary Element Method (DRBEM). It is proven to be able to provide a computationally ... 詳細を見る
Shape Optimization of Electric and Magnetic System using Level Set Technique and Sensitivity Analysis
The classical optimization method has been applied to many design problems for electromagnetic systems. One of its major difficulties is related to meshing problems arising from shape modifications. In order to circumvent these kinds of technical difficulties with moving mesh problems, ... 詳細を見る
Material Characterization Method Development: From Education to Design Optimization
Introduction of silicone hydrogel contact lens materials provided products of unprecedented capability to deliver oxygen to the eye during wear. One additional material characteristic of interest is the material’s permeability to ions. This paper discusses descriptive tools and ... 詳細を見る
Smoothing the Path to Simulation-Led Device Design
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 ... 詳細を見る
Modeling Linear Viscoelasticity in Glassy Polymers using Standard Rheological Models
In this study, a capability has been developed for modeling the linear viscoelastic behaviour of a glassy polymer using COMSOL Multiphysics®. The two rheological models by Maxwell and Kelvin-Voigt were used for modeling stress relaxation and creep loading behavior, respectively, of a ... 詳細を見る
