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 Particle Tracing for Fluid Flow interface is used to compute the erosion of a pipe bend. The amount of material lost is computed using different erosion models. Read More
Porous materials are frequently represented through periodically arranged microstructures. To compute porous media flow, the macroscale permeability and porosity is used which can be calculated from the creeping flow results through the microscale unit cell. In this application, various ... Read More
The level set method is well suited for problems with moving boundaries in which the geometry’s topology changes with time. A bubble of oil that travels up through water and finally merges with oil at the top causes this kind of topology change. For problems where the topology is ... Read More
This example of turbulent flow in a partially baffled turbulent mixer with a three-bladed impeller shows how to set up the Rotating Machinery, Turbulent Flow interfaces from the Mixer Module with a Level Set method for free surface flow in a rotating geometry. A time-dependent simulation ... Read More
When cooking food, such as a patty, in convection ovens there is a trade off in the heating method. If the patty is heated at a low oven temperature the cooking is slow and the patty dries out, resulting in a poor taste. If the patty is heated rapidly at a high temperature, it is ... Read More
This example is a model of a continuous casting process. Liquid metal is poured into a mold of uniform cross section. The outside of the mold is cooled and the metal solidifies as it flows through. When the metal leaves the mold, it is completely solidified on the outside, but still ... Read More
High-power battery energy storage systems (BESS) are often equipped with liquid-cooling systems to remove the heat generated by the batteries during operation. This tutorial demonstrates how to define and solve a high-fidelity model of a liquid-cooled BESS pack which consists of 8 ... Read More
This example solves the heat transfer in an isothermal box aimed at transporting refrigerated articles such as medical materials for 24 hours. In this case, the box has to keep the contents cold for a long period of time while respecting storage temperature restrictions between 2°C and 8 ... Read More
This example shows how to set up a glacier flow model in principle, containing several important aspects of glacier modeling: The creation of the 2D geometry, the modeling of non-Newtonian flow, and the implementation of basal sliding. In this example, two different glacier types, a cold ... Read More
This app demonstrates the following: Geometry parts and parameterized geometries Sending an email with a report when the computation is finished User-defined email server settings which is useful when running compiled standalone applications Options for setting different mesh sizes ... Read More
