The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. To download the MPH-files, log in or create a COMSOL Access account that is associated with a valid COMSOL license. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
Caughey-Thomas Mobility
With an increase in the parallel component of the applied field, carriers can gain energies above the ambient thermal energy and be able to transfer energy gained by the field to the lattice by optical phonon emission. The latter effect leads to a saturation of the carriers mobility. The ... Read More
Modeling a Koch Snowflake
This example exemplifies how to model a Koch snowflake using the Application Builder. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "[Using the Application Builder to Create a Koch Snowflake](https://www.comsol.com/blogs/using-the-application-builder-to-create-a-koch-snowflake/) ...

1D Step Bearing
This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic step bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. Read More
Electrical Heating in a Busbar Assembly
This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between Solid Edge and COMSOL, how to modify the geometry from COMSOL, and how to run a geometric parametric sweep. Read More
Maximizing the Buckling Load of a Diagonal Brace
Buckling is a common failure mode for slender structural components. This model shows how the buckling load of a diagonal brace can be maximized, while constraining the volume of the brace. Read More
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 ... Read More
Recursion and Recursively Defined Geometry Objects
You can use the Method Editor in the Application Builder for creating methods that perform almost any type of modeling tasks, including geometry modeling. It is easy to miss the fact that methods can support recursion by having a method calling itself in a recursive loop. Here, we will ... Read More
Vortex Lattice Formation in a Rotating Bose–Einstein Condensate
This tutorial model solves the Gross–Pitaevskii Equation for the vortex lattice formation in a rotating Bose–Einstein condensate bound by a harmonic trap. The equation is essentially a nonlinear single-particle Schrödinger Equation, with the inter-particle interaction represented by a ... Read More
Fast Modeling of a Transmission Line Wilkinson Power Divider
Some conventional three-port power dividers are resistive power dividers and T-junction power dividers. Such dividers are either lossy or not matched to the system reference impedance at all ports. In addition, isolation between two coupled ports is not guaranteed. The Wilkinson power ... Read More
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. Read More
