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. 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.
This example simulates the thermodynamical evolution of moist air in an electronic box with the aim of detecting whether condensation occurs when the external environment properties change. The model imports measured data for the air temperature, pressure, and water vapor concentration. ... Read More
Magnetic resonance imaging (MRI) systems generate a magnetic flux density (B-field) to create images. Providing a homogeneous field distribution within a birdcage coil is a key factor for improving the quality of the scanned data. A homogeneous magnetic field can be found through ... Read More
This model demonstrates how the Free Shape Boundary feature can be used to perform shape optimization on a design found with topology optimization. The model uses the same objective and constraint as the original, which results in a slightly higher stiffness for the same mass. Read More
This model presents a time-dependent study of a microchannel that is used to infuse and flush another piece of equipment with a fluid. The pressure at the five inlets varies sinusoidally as functions of time, and the velocity vector at the outlet is studied. The model uses an ... Read More
Electrical components in wireless communication systems are designed to be small and light for portability and productivity while maintaining decent performance and efficiency. Antennas are essential components in mobile devices and are required to fit in the limited space allowed by ... Read More
This app demonstrates the following: Dynamic help system using card stacks Multiple components (1D and 3D) in a single app Toggle buttons in the ribbon for showing different input, hiding/showing geometry selections, and for dynamic help Geometry parts and parameterized geometries ... Read More
This app demonstrates the following: Visualizing material appearance, color, and texture Showing info below the graphics about geometry parameters, results and performance depending on the selected plot action Thermoelectric coolers are widely used for electronics cooling in various ... Read More
Passive devices can be designed using lumped element features if both the operating frequency of the device and the insertion loss of lumped elements are low. This example simulates two types of lumped element filters that are similar to lumped ports, except that they are strictly ... Read More
This tutorial demonstrates how an electrical circuit model of a MEMS resonator can be derived using the Parameter Estimation feature. The model is a modified Butterworth-Van Dyke circuit created using the Electrical Circuit interface and represents a Thin-Film Bulk Acoustic Resonator ... Read More
This app demonstrates the following: Creating apps for small screens such as smartphones User-interface navigation with a top menu typically used on websites Dynamically hiding forms using card stacks to minimize the space required by the app Changing appearance by using different ... Read More
