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.
In this tutorial model, an eigenvalue analysis of a turbocharger rotor is performed. The rotor is analyzed in an unconstrained configuration, also commonly known as free–free conditions. A rotor like this is usually intended for high-speed applications, but here the analysis is performed ... Read More
This application illustrates a modeling approach for deriving physically consistent simplified models in the Acoustics Module. The approach consists of converting complex sub-components to an impedance boundary condition and otherwise using simple acoustics throughout the COMSOL model. ... Read More
The miniaturization of electronics devices requires batteries with higher energy density and power. To increase the contact area between the electrodes and the solid electrolyte, 3D configurations such as the trench geometry are used. This example demonstrates how to model a solid-state ...

A waveguide filter is designed using shape optimization by moving and scaling rectangles in the geometry. The irises of the initial geometry are optimized to ensure good bandpass response and out-of-band rejection, while maintaining the double mirror symmetry. The EGO optimization solver ... Read More
This tutorial shows how to simulate coupled heat and moisture transport in a wall. The wall is modeled considering an air flow between interior and exterior varying with time. The 1D model is the third benchmark test defined in HAMSTAD-WP2 Modeling for the validation of numerical ... Read More
The sound distribution from a TV in a two-room apartment is computed. The simulation demonstrates the use of the Acoustic Diffusion Equation interface to get a quick and simple estimate of the local sound pressure level. For increased accuracy, an analytical expression for the direct ... Read More
Find the optimal cross section areas of trusses in a structure given a prescribed set of limitations and a clear objective. The structure is made up of trusses which are elements that can only sustain axial forces. 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
The purpose of this model is to demonstrate pure rolling of a rigid wheel when given an initial forward velocity together with a prescribed lean about this direction. It is assumed that the the rolling motion of the wheel is not affected by contact such that all three components of the ... Read More
The Turbulent flow, Elliptic Blending R-ε interface is used to analyze fully developed turbulent flow in a spanwise rotating channel. Due to the influence of the Coriolis force on turbulence, profiles of the flow variables are skewed at moderate rotation rates. An asymmetry between the ... Read More
