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 backward facing step is an interesting case for studying the performance and solution strategy of a turbulence model. In this case, the flow is subjected to a sudden increase of cross-sectional area, resulting in a separation of flow starting at the point of expansion. Spatial ... Read More
This example shows how to set up multiple sandwiched thin layers with different thermal conductivities in two different ways. First, the composite is modeled as a 3D object. In the second approach the Thin Layer boundary condition with the thermally thick option is used to avoid ... Read More
The drive for miniaturizing electronic devices has resulted in today’s extensive use of surface-mount electronic components. An important aspect in electronics design and the choice of materials is a product’s durability and lifetime. For surface-mount resistors and other components ... Read More
This model uses the discrete-ordinates method (DOM) to analyze the radiative heat transfer in a utility boiler with internal obstacles. DOM is one of the most useful radiation models for prediction of radiative heat fluxes on the furnace walls of a combustion chamber. With this model, ... Read More
Gas cells have several applications in the design of scientific instruments. A gas cell is used to define a high-pressure region within the instrument's main vacuum system. For example, in this application, note we are designing a high-pressure region 100 mm long, with an operating ... Read More
Tutorial model of an air-cooled battery energy storage system (BESS). The model includes conjugate heat transfer with turbulent flow, fan curves, internal screens, and grilles. It features several interesting aspects: Fully parameterized geometry, which can be modified for different ... Read More
This app demonstrates the following: A model using symmetry while the results are visualized in full 3D Provides info if the results are above or below certain critical values Selecting predefined or user-defined materials Error control of geometry parameters using methods and ... Read More
This example demonstrates simulation of a turbulent flow in a geometry with an air filter. Porous material of the filter induces an abrupt pressure drop and drastic increase of turbulence level inside the filter. Read More
A propeller is the propulsion device of a ship. This model studies the open water performance of the KP505 propeller[1]using the frozen rotor method with RANS turbulence model. Thrust and torque coefficient, and open water efficiency of the propeller at different advance coefficients ... Read More
This model solves the fluid flow and heat transfer in a micro heat exchanger made of stainless steel. These types of heat exchangers are found in lab-on-chip devices in biotechnology and micro reactors, for example for micro fuel cells. The model takes heat transferred through both ... Read More
