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.
Electrochemical supercapacitors feature relatively higher energy densities than conventional capacitors. With several advantages, such as fast charging, long charge–discharge cycles, and broad operating temperature ranges, electrochemical supercapacitors have found wide applications in ... Read More
In static mixers, also called motionless or in-line mixers, a fluid is pumped through a pipe containing stationary blades. This mixing technique is particularly well suited for laminar flow mixing because it generates only small pressure losses in this flow regime. This example studies ... Read More
Dialysis is a widely used chemical species separation method. One such example is hemodialysis, which acts as artificial kidneys for people with renal failure. In dialysis, only specific components are allowed to diffuse through the membrane, based on differences in molecular size and ... Read More
This tutorial example serves as an introduction to the Corrosion Module and models the metal oxidation and oxygen reduction current densities on the surface of a galvanized nail, surrounded by a piece of wet wood, which acts as electrolyte. The protecting zinc layer on the nail is not ... Read More
When several components are to be electroplated they are typically mounted on a rack in the electroplating bath. An important aspect is then achieving a uniform thickness of the plated layer for all components mounted on the rack. This example model allows for investigating the effect ... Read More
In this example, drug-release from a biomaterial matrix to damaged cell tissue is modeled. Specifically, a nerve guide delivers a regenerating drug to damaged nerve ends. The model involves detailed drug release kinetics, with rate expressions handling drug dissociation/association ... Read More
This tutorial demonstrates the Lumped Battery interface for modeling capacity loss in a battery. A set of lumped parameters are used to describe the capacity loss that occurs due to parasitic reactions in the battery, assuming no knowledge of the internal structure or design of the ... Read More
This tutorial uses a “black-box” approach to define a battery model based on a small set of lumped parameters, assuming no knowledge of the internal structure or design of the battery electrodes, or choice of materials. The input to the model is the battery capacity, the initial state ... Read More
In an alkaline electrolyzer stack, all cells share the same electrolyte. As a result of all cells being in ionic contact, parasitic shunt currents flow between the cells through the manifolds and the electrolyte channels, on both the inlet and outlet side. This example models a ... Read More
In this application, a solution is pumped through a catalytic bed where a solute species reacts as it gets in contact with the catalyst. The purpose of this example is to maximize the total reaction rate for a given total pressure difference across the bed by finding an optimal catalyst ... Read More
