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.
FEM simulation can be used to obtain a SAW velocity and some related parameters (squared electromechanical coupling coefficient, reflectivity, etc.) for different typical configurations. Such parameters are input data for various analytical and semi-analytical methods of SAW device ... Read More
This tutorial shows how to model a miniaturized magnetostrictive antenna developed for use inside living cells. The stress in the antenna, the magnetic flux density, the current density, and the displacement of the tip of the device are investigated at the resonance frequency. Read More
A detailed description of these models can be found in our blog post “How Should I Evaluate Singular Stress Fields?”. The models are: notchedStrip.mph – Model for the initial studies of the stress field properties. singularityPower.mph – Small model solving the transcendental equation ... Read More
This example shows how to set up an ionic polymer-metal composite (IPMC) as an actuator for a robotic manta ray. Two IPCM beams are integrated into the fin and can be controlled independently. The chemomechanical effect is achieved with the Shrinkage and Swelling multiphysics ... Read More
This model analyzes Joule heating and thermal expansion in a bond wire in an LED. Its purpose is to estimate the temperature increase and the resulting mechanical stresses in the bond wire due to thermal expansion. The magnitude of these stresses can be used to assess the risk of fatigue ... Read More
For models with acoustic-structure couplings it is necessary to calculate the left eigenvectors to use the Frequency Domain, Modal solver. The model shows the necessary changes to the default settings of the eigenfrequency solver. Read More
This example shows how to model Lithium diffusion in a silicon electrode that swells. The model shows how swelling-induced plastic deformation can increase the maximum state of charge (SOC). Read More
As integrated circuit (IC) technology advances, with circuits becoming more powerful and compact, it is increasingly important to identify and prevent any cause of circuit failure. One particularly critical factor contributing to circuit failure is electromigration within the ... Read More
This model demonstrates 2D topology optimization for the problem of minimum mass subject to a compliance constraint and a stress constraint. The stress constraint is implemented with a P-norm global aggregation function. The stress input to this is interpolated differently than the Young ... Read More
The purpose of this application is to generate response spectra from a time history which can consist of either measured data on a file, or an analytical function. Primarily, the target is to provide input to a response spectrum analysis. The graphs can, however, also be used to ... Read More
