Pacemaker Electrode

This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in SolidWorks by using the LiveLink interface.

Electrode Growth Next to an Insulator

This example shows how to model secondary current distribution and electrode growth with a moving geometry. To avoid numerical instabilities, a seed layer is introduced in the initial geometry to obtain a right angle at the edge between the growing electrode and the insulator.

Harmonic Content of the Power Deposition into a Dual Frequency Capacitively Coupled Plasma

Energy transfer from the time varying electrostatic field to electrons in a capacitively coupled plasmas (CCP) does not exclusively occur at twice the RF frequency. Due to the highly nonlinear mechanism of power transfer from the fields to the electrons, power deposition occurs at frequencies higher than twice the driving frequency. For dual frequency CCP reactors the harmonic content of the ...

Space-Dependent HI Reactor

This model deals with a reacting system comprising of an equimolar mixture of hydrogen and iodine gas which is allowed to react and form HI. Composition and temperature are allowed to vary both in space and time. This means that you have to define material balances, energy balances, and transport properties in the Reaction Engineering interface. These balances and properties are exported to ...

Outgassing Pipes

This benchmark model computes the pressure in a system of outgassing pipes with a high aspect ratio. The results are compared with a 1D simulation and a Monte-Carlo simulation of the same system from the literature.

Hexagonal Grating (RF)

A plane wave is incident on a reflecting hexagonal grating. The grating cell consists of a protruding semisphere. The scattering coefficients for the different diffraction orders are calculated for a few different wavelengths.

Disc Resonator Anchor Losses

This model shows how to compute the anchor loss limited quality factor of a diamond disc resonator. The resonator is anchored to the substrate by a polysilicon post and power is transmitted to the substrate through the post. A perfectly matched layer is used to represent the essentially infinite substrate. The model is based on a paper presented at the 2007 COMSOL conference in Grenoble: P. ...

Primary Creep Under Nonconstant Load

In this model example, you will study the creep behavior of material under non-constant loading. You will model the primary creep using a Norton-Bailey law and study the difference between the time hardening and the strain hardening methods available in COMSOL Multiphysics. The model is taken from NAFEMS Understanding Non-Linear Finite Analysis Through Illustrative Benchmarks. The load consist ...

Modeling a Conical Dielectric Probe for Skin Cancer Diagnosis

The response of a millimeter wave with frequencies of 35 GHz and 95 GHz is known to be very sensitive to water content. This model utilizes a low-power 35 GHz Ka-band millimeter wave and its reflectivity to moisture for non-invasive cancer diagnosis. Since skin tumors contain more moisture than healthy skin, it leads to stronger reflections on this frequency band. Hence the probe detects ...

Electrical Heating in a Busbar

This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between Inventor and COMSOL, how to modify the geometry from COMSOL, and how to run a geometric parametric sweep.
