Isolator Thickness Effect

The use of Aluminum (Al) isolator is a commonly employed mitigation strategy for galvanic corrosion between magnesium alloy (Mg) and mild steel (MS). The present model demonstrates the effect of Al isolator thickness on galvanic corrosion severity using a parametric study. The electrode kinetics is implemented here using the experimental polarization data available in literature.

Geometric Parameter Optimization of a Tuning Fork

This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Creo Parametric via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz.

Using Text Files to Automate Model Preprocessing

This example exemplifies how to set-up text files to use when preprocessing models that contain hundreds of parts. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "[Automate Model Preprocessing with the Application Builder](https://www.comsol.com/blogs/automate-model-preprocessing-with-the-application-builder/)".

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.

Rotating Plate in a Unidirectional Molecular Flow

This model computes the particle flux, number density and pressure on the surface of a plate that rotates in a highly directional molecular flow. The results obtained are compared with those from other, approximate, techniques for computing molecular flows.

Electrical Heating in a Busbar

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

Lombardi Surface Mobility

Surface acoustic phonons and surface roughness have an important effect on the carrier mobility, especially in the thin inversion layer under the gate in MOSFETs. The Lombardi surface mobility model adds surface scattering resulting from these effects to an existing mobility model using Matthiessen’s rule. This model demonstrates how to use the Lombardi surface mobility model for the electron ...
