Simulation Methods and Teaching

Integrating COMSOL into a Mathematical Modeling Course for Chemical Engineers

A. Dixon, and D. DiBiasio
Department of Chemical Engineering, Worcester Polytechnic Institute, Worcester, MA, USA

The multiphysics simulation package COMSOL was incorporated into a course in mathematical modeling for chemical engineers. Our implementation for the first year of using COMSOL in the course is described, and assessment results based on examinations and student survey results are ... En savoir plus

Stability Analysis of ALE-Methods for Advection-Diffusion Problems

A. Weddemann, and V. Thümmler
Bielefeld University, Germany

ALE-methods are frequently used to solve systems of partial differential equations (PDEs) on moving domains. The main idea of these methods is to incorporate the time evolution of the domain into the equations. However, the motion of the domain with respect to time induces convective ... En savoir plus

Numerical Demonstration of Finite Element Convergence for Lagrange Elements in COMSOL Multiphysics

M. Gobbert, and S. Yang
Department of Mathematics and Statistics, University of Maryland, Baltimore, MD, USA

The convergence order of finite elements is related to the polynomial order of the basis functions used on each element, with higher order polynomials yielding better convergence orders. However, two issues can prevent this convergence order from being achieved: the lack of regularity of ... En savoir plus

COMSOL Multiphysics Models for Teaching Chemical Engineering Fundamentals: Absorption Column Models and Illustration of the Two-Film Theory of Mass Transfer

W. Clark
Chemical Engineering Department, Worcester Polytechnic Institute, Worcester, MA, USA

COMSOL® models have been developed for teaching gas absorption fundamentals. Model results are compared to environmentally significant experimental results for removing CO2 and SO2 from air using water as solvent. For concentrated gas mixtures, the models are shown to be equivalent to ... En savoir plus

Resonating with Students in the Undergraduate Physics Laboratory: Comprehending Acoustic Vibrations

K. Stein, R. Peterson, J. Houlton, J. Knapp, B. Peplinski, C. Scheevel, and D. Swenson
Department of Physics, Bethel University, St. Paul, MN, USA

Acoustic vibrations are studied for several objects through the application of computational and optical diagnostic techniques. Computational studies are carried out using the eigenfrequency analysis option in the COMSOL structural mechanics application mode, whereas experimental optical ... En savoir plus

Weak Form & LiveLink™ for MATLAB® Based Modified Uzawa Method For Solving Steady Navier-Stokes Equation

H. Sheng[1], S. Zhu[1]
[1]Shanghai Jiaotong University, Minhang, Shanghai, China

We demonstrate a simple example about how to design my own algorithm for Navier-Stokes equation by weak form PDE and LiveLink™ for MATLAB®. After the computation, we get the same solution as other FEM packages (FreeFEM++ & FeniCs) at each iterative step, and we can see the Navier ... En savoir plus

Electromagnetic Well Logs Simulated with the COMSOL® RF Module on a Cluster

D. Swaminathan[1], G. Minerbo[1], K. Pathak[1]
[1]Drilling and Production Group, Schlumberger, Houston, TX, USA

Introduction Computer simulations are widely used for the interpretation and inversion of electromagnetic measurements in well logging. Until recently, simulated logs have been computed with approximate 1D or 2D models. By using the COMSOL® RF Module installed on a cluster, we show that ... En savoir plus

Models of Simple Iron Cored Electromagnets

J. Mammadov[1]
[1]University of Manchester, Manchester, UK

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 ... En savoir plus
