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.
In these tutorial series, we demonstrate how to use the Offset Faces and Transform Faces operations as a way to reparameterize existing holes in a bracket geometry imported from a STEP file. The mass of the bracket is minimized with limits for both the lowest natural frequency, and for ... Read More
Due to the demand for larger power with a smaller size, dual-shaft systems with intershaft bearings are becoming a standard configuration for gas turbine engines. Such systems consist of two coaxial rotors running at different speeds, interlinked through a multi-spool bearing. In this ... Read More
Nowadays, there is a trend to manufacture wheel rim made up of a composite material instead of aluminum. The primary reason is to have lower values of unsprung mass which leads to faster response time and thus better acceleration, braking and cornering performances. Typically a carbon ... Read More
Different types of elements can be used for modeling a rotor, depending on the level of complexity and the type of the system being modeled. The modeling steps and representation of the results will vary with the type of idealization. In this tutorial model, an eigenfrequency analysis is ... Read More
This benchmark demonstrates how to use the Beam interface in the Structural Mechanics Module. It calculates the deformation, section forces, and stresses in a cantilever beam as well as a number of eigenfrequencies. It also illustrates how to use the Beam Cross Section interface to ... Read More
This tutorial illustrates how to use a reduced order model to compute the response of a structure subjected to three simultaneous loads having independent time histories. Reduced order models provide an efficient way to analyze problems within linear structural dynamics. Read More
In this example, learn how to model two rotors connected by a spline coupling. The first rotor is a fixed cantilevered rotor and the second rotor is supported. The model assumes that only translational motion is coupled between the rotors through the coupling, while the rotations of both ... Read More
This example explores the shift in natural frequencies caused by changing the temperature. One study investigates a doubly clamped beam where both ends are fixed, while the other study looks at a cantilever beam where only one end is fixed. The following effects are studied: Stress ... Read More
The stresses in a pulley connected to an engine that drives another pulley are studied in this model. A parametric analysis is conducted in order to study how the rotational speed affects the stress distribution in the pulley. The power at the pulley shaft remains constant, the moment ... Read More
In this tutorial model, you will see how to set up an eigenfrequency analysis of a rotor with multiple disks and bearings. The example illustrates how to use Campbell and stability diagrams to identify the critical speeds and the stability threshold. The rotor is modeled using the Beam ... Read More
