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.

Time-Limited and Hardware-Locked Application

This example shows how to create a time-limited and hardware-locked application. It is associated with the section "Time-Limited and Hardware-Locked Applications" in the _[Application Programming Guide](/documentation/ApplicationProgrammingGuide.pdf)_ (page 196). Read More

Step Thrust Bearing

In this tutorial model, a six step thrust bearing is analyzed. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be spinning without any axial motion in the ... Read More

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. Read More

Geometric Parameter Optimization of a Tuning Fork

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

Quasi-2D Turbomolecular Pump

The Monte Carlo simulation of flow in a turbomolecular pump can be greatly simplified if the mean radius of the blades is much greater than the spacing between them. Under these conditions, the rotating blades of the pump can be approximated as an infinite row of blades having only ... 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 Solid Edge by using the LiveLink interface. Read More

SmartUQ Engineering Analytics Light-Weighting Application with COMSOL FEA Bracket Example

For decades, light-weighting has been a major area of research and concern in the automotive and aerospace industries. Industry leaders are adopting new software tools and investing ever greater engineering resources in adapting and optimizing their designs to be as lightweight and ... Read More

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

Modeling Current Distribution in a 3D Lead-Acid Battery Grid Battery new

This 3D model example demonstrates the use of the Lead-Acid Battery interface for modeling current distribution in full cell employing a lead-acid battery chemistry. The lead acid battery chemistry uses PbO2 as the positive porous electrode and Pb as the negative porous electrode and ... Read More
