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.
The model shows how to estimate the Young's modulus and Poisson ratio based on a tensile test. The test measures the tensile force and the radial displacement. Typical numerical values of these quantities differ with around 10 orders of magnitude. Using a maximum likelihood strategy ... Read More
Helmholtz resonators are used in exhaust systems, as they can attenuate a specific narrow frequency band. The presence of a flow in the system alters the acoustic properties of the resonator and the transmission loss of the subsystem. In this tutorial model, a Helmholtz resonator is ... Read More
Many robot vacuum cleaners nowadays are equipped with lidar for spatial mapping in order to design an optimal cleaning path and navigate in a room without bumping into obstacles. This model simulates the lidar of a robot vacuum cleaner and how it maps out the shape of the room using ... Read More
This model simulates the mixing of two types of grains in a rotating drum with baffles. The effect of the number of baffles on the mixing is demonstrated by varying the number of baffles in the drum. This model also demonstrates how to build and run a model method that evaluates the ... Read More
This model demonstrates how to create a rotated helix geometry, i.e., a helix that is winded to form a torus. This is done sweeping a circle along a parametric curve. The radius of the torus and the radius of the coil are given as parameters as well as the number of windings of the coil. Read More
A magnetic diaphragm is a flexible, thin structure that interacts with magnetic fields to perform mechanical or sensing functions. When subjected to an external magnetic field, the diaphragm deforms due to magnetomechanical interactions, converting magnetic energy into mechanical ... Read More
This model shows the workflow to define a transfer orbit trajectory with user defined orbit option. The direct solar, albedo, and Earth radiative thermal loads are analyzed during the transfer from low Earth orbit to geostationary orbit. Read More
This model demonstrates the simulation of surface dielectric barrier discharges (DBDs) using the Electric Discharge interface. The formulation incorporates a comprehensive set of physical processes, including charge transport, impact ionization, electron attachment, recombination, and ... Read More
Inverted elements can prevent large deformations for shape optimization. This model demonstrates how this problem can be circumvented using export/import of the geometry and a model method. The technique is demonstrated on a benchmark problem from topology optimization, where the ... Read More
This tutorial shows how to simulate coupled heat and moisture transport in a wall made of a load bearing and an insulation layer. Moisture and temperature conditions vary with time on both sides of the wall and rain loading is included. The 1D model is a benchmark test defined in ... Read More
