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.

Electrodeposition on a Resistive Patterned Wafer

This example models time-dependent copper deposition on a resistive wafer in a cupplater reactor. As the deposited layer builds up, the resistive losses of the deposited layer decreases. The benefit of using a current thief for a more uniform deposit is demonstrated. Read More

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

Evanescent Mode Cylindrical Cavity Filter

An evanescent-mode cavity filter is resonant at a frequency lower than its original fundamental mode frequency. Evanescent mode resonance can be realized by creating a discontinuity or reactance inside the cavity. The basic model was modified by the addition of a metal box at either ... Read More

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 ...

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

Cluster Setup Validation

Use this app to validate that the default settings correctly submit jobs to a cluster. These default settings are taken from the preferences. The app allows you to override the default cluster settings, test modifications to the current setup, and test different settings for connecting ... Read More

Critical Speed of a Dual Rotor System

Due to the demand for larger power with a smaller size, dual-shaft systems with intershaft bearings are becoming a standard configuration for gas turbine engines. Such systems consist of two coaxial rotors running at different speeds, interlinked through a multi-spool bearing. In this ... Read More

Superfilling Electrodeposition

This example illustrates the concept of superfilling in electrodeposition. The deposition rate is accelerated in concave areas of the surface, where the concentration of a surface catalyst is increased due to the area contraction of the moving boundary. Read More

Beam Section Calculator (Using LiveLink™ for Excel®)

This app demonstrates the following: * Reading and importing data from an Excel®-file * Exporting data to an Excel®-file * Light theme The app computes the beam section properties and true stress distribution in a designated steel beam section. A broad range of American and European ... Read More

Shape and Topology Optimization of Compliant Pliers

Compliant mechanisms are attractive due to their simplicity, owing to their lack of hinges. In this model we show how to design a set of compliant pliers using topology optimization. The resulting design is post-processed using shape optimization, where the maximum stress is constrained ... Read More
