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 shows how to perform a topology optimization with several load and constraint cases. The density feature for topology optimization is used together with a parametric sweep where each optimized solution is used as input for a further improved optimization. The final ... Read More
This example focuses on the species transport within the gas diffusion layers (GDLs) of a proton exchange membrane (PEM) fuel cell. The geometry models a cell with two adjacent flow channels of different pressures, a situation that may occur in a cell with serpentine flow channels, or in ... Read More
This is a small 2D demonstration model that couples the Linearized Navier-Stokes, Frequency Domain, Solid Mechanics, and Turbulent Flow (k-epsilon) physics interfaces to model the vibrations of a plate located in a 2D viscous parallel plate flow. This type of model is used to model fluid ... Read More
This model analyzes the nonlinear transfer impedance of a tapered orifice that can be part of a perforate or microperforated plate (MPP). The analysis is carried out for various degrees of tapering of the perforate and for a frequency range. A linear analysis is set up in the frequency ... Read More
The following example is a 2D tutorial model of a lithium-ion battery. The cell geometry is not based on a real application; it is only meant to demonstrate a 2D model setup. Read More
This tutorial model demonstrates the use of the multiphysics coupling feature Thermal Connection, Layered Shell, Surfaces. In this model, three layered shells are connected to heat domains by interior and exterior boundaries. The results obtained with the Heat Transfer in Shells ... Read More
This series of models demonstrates how to do advanced electric machine modeling with COMSOL Multiphysics® — in 2D, 2.5D, and full 3D with end effects included. It investigates the performance of a Permanent Magnet Synchronous Motor, as is often used in modern electric vehicles. ... Read More
This model shows a full vibroacoustic analysis of a loudspeaker including driver, cabinet, and stand. It lets you apply a nominal driving voltage and extract the resulting sound pressure level in the cabinet and in the outside room, as well as the deformation of the cabinet and driver, ... Read More
This model shows how shape optimization can be used design the coils of an ICP reactor to obtain plasma uniformity. The reactor in study is a planar ICP with the coils distributed along the radial direction. The Optimization study step is used to find the best coil placement so that the ... Read More
This example describes how to simulate the self-lubricating phenomenon of a liquid lubricant in a journal bearing. A porous bushing is press-fitted to a bearing and saturated with a lubricant. It acts as a reservoir for the redistribution of the thin film of lubricant between regions of ... Read More
