2D-Cyclic Voltammetry Model: 1 electron 2 speicies dillute diffusion

Robert Palumbo, Valparaiso University
Last updated: June 25, 2012

6 reviews

A simple COMSOL mph cyclic voltammetry (CV) 2D time-dependent model was developed. The model presumes the electrode kinetics are described by a 1 electron transfer process. The transport of a...

Another Pandulum (3d truss element)

Yalcin Kaymak, VDEh-betriebsforschungsinstitut
Last updated: April 18, 2012

3 reviews

Pandulum model using 3d truss element. initial position is from (0,0,0) to (0,2,10). (0,2,10) end is pinned. (0,0,0) end has 10kg mass. gravity is applied in -z direction. analitical solution...

1D resonant quantum tunneling

Per Sundqvist, ABB Corporate Research AB
Last updated: February 28, 2012

4 reviews

The model sets up boundary conditions for the Schrödinger equation in order to achive tunneling solutions. A resonant barrier potential is created with 1nm separation-width and 0.2nm oxide...

Zernike Polynomial extraction of deformed optical surface

Ivar Kjelberg, CSEM sa
Last updated: February 28, 2012

1 review

You will find hereby a COMSOL Multiphysics v4.2a Solid + Optimisation model extracting the first dozen Zernike polynomials from a deformed circular surface, expressed in RMS values. In optics,...

Pyramidal Horn Antenna

Robert Koslover, SARA, Inc.
Last updated: February 8, 2012

8 reviews

We provide a convenient 3D RF model of a generic pyramidal microwave horn, with a simple user-adjustable (parameterized) geometry. The model was prepared with Comsol Multiphysics v4.2a with the RF...

2D transient pressure field from a boundary

Robert Malkin, University of Bristol
Last updated: January 17, 2012

1 review

This very simple 2D transient model uses the Acoustic Module to show how a pressure wave propagates in time. The scenario is a simple 2D rectangle with one boundary acting as the source of the...

Loudspeaker Driver Electromagnetic v4.1

Loic Queval, University of Tokyo
Last updated: May 27, 2011

1 review

This model is the electromagnetic part of the Loudspeaker Driver model (http://www.comsol.com/showroom/gallery/1369/). The acoustic module is NOT required to open this model.

Low Reynold's k-epsilon model for Comsol v3.5

Laith Hurmez, University of Auckland
Last updated: March 30, 2011

2 reviews

This implemented Low-Re k-epsilon Comsol model is based on the Launder-Sharma damping functions as described in Wilcox's Turbulence modeling for CFD book. Model implementation was in 2D under...

5 reviews

CoBoGUI is a freely available collection of MATLAB scripts for two dimensional solar cell simulations with COMSOL Multiphysics and MATLAB. It proviedes a flexible graphical user interface and...

SPICE RCL-circuit with initial conditions

Per Sundqvist, ABB Corporate Research AB
Last updated: October 5, 2010

14 reviews

This model shows how to set up a SPICE model of a RCL-circuit in COMSOL4.0a with other initial conditions than default. The SPICE (Electric Circuit, "cir") in COMSOL does not allow you to...
