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.
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
This model presents a method to analyze acoustic damping pads. These pads use a constrained layer of viscoelastic material to dissipate energy and thus reduce the energy radiated as noise. Damping pads are used in many different industries to reduce the noise generated by vibrating ... Read More
The ball grid array (BGA) technology is a surface-mount technology widely used in electronic packaging. Usually, there are two types of solder balls considered in the array, including the functional balls that are required for electric connections and the support balls that are used only ... Read More
In his example, the lowest natural frequency of a 3D bracket are maximized using shape optimization. Read More
This conceptual example shows how to calculate critical points in models with contact. The model consists of two contacting arches modeled with the Shell interface. The contact problem is solved using the penalty method. The upper arch is loaded with displacement controlled edge loads ... Read More
The reliability of a bike frame can be estimated by analyzing the structural stress subjected to different load cases. This app leverages LiveLink™ for SOLIDWORKS® to interactively update the geometry while computing stress analyses. Using this app, you can easily test different ... Read More
These models illustrate some important topics when modeling buckling imperfection. The Euler 2 Buckling Imperfection model shows a simple case with a cantilever beam buckling under compression. Three different buckling modes are combined as initial imperfections. The other model, ... Read More
This example illustrates how to perform eigenfrequency and static analyses of a ladder frame structure for a light truck. Important modeling strategies are described. For example, how to convert a solid geometry to a shell model, how to make different types of connections, and how to ... Read More
In this model, you build and solve a 2D beam model using the 2D Structural Mechanics Beam interface. This model describes the eigenfrequency analysis of a simple geometry. A point mass and point mass moment of inertia are used in the model. The two first eigenfrequencies are compared ... Read More
In this example, the External Stress feature in the Solid Mechanics interface is used to provide the material model with the nonsymmetric stress required in the design of an elastic invisibility cloak. The cloak is a domain with special material properties aimed at shielding a region of ... Read More
