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.
A 3D model of an acoustic trap in a glass capillary with a bias flow through the capillary. The acoustics is actuated by an oscillating electric potential across a piezoelectric transducer, inducing mechanical vibrations in the solid, and an acoustic pressure field in the fluid. The heat ... Read More
The standard biventricular cardiac model is used to show how to set up fiber directions in a complex geometry. The fibers are then used to model the large deformation of the myocardium with the Holzapfel-Gasser-Ogden anisotropic material model. The Aliev-Panfilov equations are included ... Read More
In many structural dynamics applications, some components are stiff compared to the supporting structure. Such a stiff part will only contribute to the dynamic properties of the structure through its mass and moment of inertia. It is then possible to reduce the model size significantly ... Read More
A tonpilz transducer is used for relatively low frequency, high power sound emission. It is one of the popular transducer configurations for SONAR applications. The transducer consists of piezoceramic rings stacked between a head mass and a tail mass which are connected by a central ... Read More
A beam splitter is used to split a single beam of light into two. One way of making a splitter is to deposit a thin layer of metal between two glass prisms. The beam is slightly attenuated within the layer, and split into two paths. In this example, the thin metal layer is modeled using ... Read More
This example demonstrates how to set up a spatially varying dielectric distribution. Here, a convex lens shape is defined via a known deformation of a rectangular domain. The dielectric distribution is defined on the undeformed, original rectangular domain and is mapped onto the deformed ... Read More
There are multiple ways to excite and terminate transmission lines using different types of port and lumped port features. In this example, transverse electromagnetic (TEM) type ports and a via type lumped port are used to simulate two adjacent microstrip lines. One via end is terminated ... Read More
Modern cars have rear-windshield FM antennas to play FM radio. The radiation emitted from an antenna induces an electric current on the outer surface of any cable harnesses in the car, which can have negative effects. This model uses the RF Module to compute the far-field radiation ... Read More
Shape optimization with respect to fatigue properties is not supported, but fatigue properties are well correlated with the maximum stress. The model demonstrates how optimization with respect to a p-norm of the von Mises stress can be used to improve fatigue properties without ... Read More
In this set of eight tutorial models and associated documentation, you can investigate the resistive, capacitive, inductive, and thermal properties of a standard three-core lead-sheathed XLPE HVAC submarine cable with twisted magnetic armor (500 mm2, 220 kV). The series includes a 2D, 2D ... Read More
