# Application Gallery

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.

### Gregory-Maksutov Telescope

The Gregory-Maksutov telescope is a simple catadioptric telescope comprising a spherical corrector lens and a spherical primary mirror. In this example the corrector lens and mirror are formed using the 'Spherical Lens 3D' and 'Spherical Mirror 3D' parts respectively from the Ray Optics ... Read More

### 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 ... Read More

### In-Plane Framework with Discrete Mass and Mass Moment of Inertia

In this model, you build and solve a 2D beam model using the 2D Structural Mechanics Beam interface. This model describes the eigenfrequency analysis of a simple geometry. A point mass and point mass moment of inertia are used in the model. The two first eigenfrequencies are compared ... 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 Solid Edge 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

### 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

### Geometric Parameter Optimization of a Tuning Fork

This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Pro/ENGINEER 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

### 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)_ 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

### Biosensor Designer for Use with COMSOL Client for Android™

COMSOL Client for Android™ is an app available in the Google Play™ store for users of COMSOL Server™. It includes features and functionality designed specifically for use with tablets and other mobile devices. The Biosensor Designer comes in two different layouts: * ... Read More

### Andrew's Squeezing Mechanism

This is a benchmark model for rigid body dynamics. This model simulates the dynamic behavior of "Andrew’s squeezing mechanism", which is force driven and requires a very small time scale. Various angles in the mechanism are compared with the results from the reference. Read More
