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

7 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...

SPICE RCL-circuit with initial conditions

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

13 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...

[SM v3.5a] Rotation constraints in structural module. With complements

Ivar KJELBERG, CSEM sa
Last updated: April 30, 2010

3 reviews

There are different boundary constraints in COMSOL structural, but in 2D/3D structural (smpn, smsld ...) there are no angular variables predefined, hence no easy way, as in the Euler beam modules,...
