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 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
This example demonstrates an app that utilizes the LiveLink™ interface for Solid Edge® to run simulations on CAD designs. Read More
This example exemplifies how to model the impedance of a waveguide of varying cross sectional area. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Computing the Impedance of a Corrugated Waveguide". Read More
This model compares the solution to the model equations of a tubular reactor using Danckwerts inlet and outlet conditions. A second almost identical model is defined with extra inlet and outlet sections where no reactions occur. The concentration at the beginning of the inlet section is ... Read More
This example uses the Granular Flow interface to model the fixed funnel method for calculating the angle of repose, where a funnel is kept at a fixed height. The funnel is first filled with grains which are subsequently released and collected as a heap. The resultant heap is then ... Read More
A demultiplexer is a device that directs different frequency bands to different outputs. In this tutorial model, we will design a demultiplexer by performing shape optimization on all initial circular boundaries in a sonic crystal (phononic crystal) configuration. The model uses shape ... 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 ...

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
This model demonstrates how to use the chatbot functionality in COMSOL Multiphysics® to add annotations to a model of a pacemaker electrode. To learn more about this model, see our accompanying blog post “Using the Chatbot Window in COMSOL Multiphysics®”. Read More
This demonstration app will fit a surface through a set of points using radial basis functions and will write out a COMSOL-format file of a smooth NURBS surface that passes through all of the points. The function describing the surface can also be written to a text file. The point data ... Read More
