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 "Smart Radiator Device," a multilayer structure, has the capability to control thermal emissivity at different temperatures. This multilayer structure is lightweight thus finds its application in spacecraft mission. The thermochromic vanadium oxide (VO2) material is the heart of ... Read More
Carbon corrosion is one of the important degradation mechanisms in a Polymer Electrolyte Membrane (PEM) fuel cells which predominantly occurs during start-up or shut down of the fuel cells. During carbon corrosion, carbon support to catalysts is compromised affecting the cell ... Read More
This example demonstrates how to use the Poroelasticity multiphysics coupling between the Solid Mechanics and Darcy's Law interfaces to model linear biphasic poroviscoelastic behavior of soft biological tissues. The implementation is verified using two numerical benchmarks from the ... Read More
This tutorial demonstrates how to modify a concentration-independent (also known as a secondary current distribution) liquid alkaline water electrolyzer with concentrated electrolyte theory to explicitly resolve local electrolyte and solvent concentrations (thereby creating a tertiary ... Read More
This is a 2D model of an anisotropic porous absorbing material. The absorption coefficient alpha are determined as functions of frequency for three different incidence angles. The example uses Periodic Floquet boundary conditions. The model uses two different methods for modeling the ... Read More
Coriolis flowmeters, also known as mass flowmeters or inertial flowmeters, measure the mass flow rate of a fluid traveling through it. It makes use of the fact that the fluid's inertia through an oscillating tube causes the tube to twist in proportion to the mass flow rate. Typically, ... Read More
In a polymer electrolyte membrane water electrolyzer cell, hydrogen and oxygen gas is produced by electrolysis. The hydrogen and oxygen compartments are separated by a polymer membrane, that also acts as electrolyte. This introductory tutorial computes the ohmic and activation losses in ... Read More
Nucleate boiling occurs when a liquid is heated by a source hotter than the saturated fluid temperature but with a heat flux below the critical heat flux. In this regime, high heat flux are possible due to the evaporation of the liquid. This model aims to demonstrate the calculation of ... Read More
Alkaline water electrolysis is a well-established industrial process for producing hydrogen gas. In the cell, hydrogen gas is formed at the cathode whereas oxygen gas is formed at the anode. The electrolyte is an aqueous liquid, and when the evolved gases form bubbles, the effective ... Read More
Wastewater treatment is a several-step process for removing contaminants. Firstly, large, solid particles are removed through sedimentation, flotation, and filtration. And then in a second step, biological treatment causes the smaller particles to aggregate, forming so called flocs. ... Read More
