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 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 model shows a full vibroacoustic analysis of a loudspeaker including driver, cabinet, and stand. It lets you apply a nominal driving voltage and extract the resulting sound pressure level in the cabinet and in the outside room, as well as the deformation of the cabinet and driver, ... Read More
Crimping is the plastic deformation process used to form an electrical joint between a stranded conductor and a terminal. The process involves complex multi-surface contact, including self-contact, as the terminal sleeve is plastically deformed around the wire strands. This example ... Read More
In the surface acoustic waves industry different crystal cuts of piezoelectric materials are used, e.g. 128ᵒ YX LiNbO3, AT&ST quartz, 42ᵒ YX LiTaO3, etc. Direct data isn’t available for all cuts. The standard approach is to use the so-called Euler angle rotation. COMSOL supports it ... Read More
The modal dispersion in a metamaterial can be engineered by changing the type of material and dimension of the composing unit cells. For instance, a periodically organized subwavelength metal–dielectric layered metamaterial exhibits an anisotropic dispersion characteristic in the ... Read More
In a cooling system, a microelectronic component has been identified as the critical link. Since the power is repeatedly switched on and off, the component is subjected to thermal cycling. As a results a crack grows through a solder joint and disconnects the chip from the printed circuit ... Read More
This model simulates arc welding of a titanium plate made from an alpha-beta titanium alloy. During a weld pass, the material experiences a thermal transient, including both heating and cooling. Phase transformations are modeled, and the evolution of the phase composition over time is ... 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 domains are modeled with thermal resistors in the Lumped Thermal System ... Read More
A Gaussian beam is incident on a 45-degree thin-film stack embedded in glass material prisms. The thin-film stack is designed from alternating high and low refractive index materials. The wave will be refracted at the Brewster angle at each internal interface. Thus, mainly p-polarized ... Read More
This model simulates a static analysis of heat conduction in a thin conductive shell. This is a benchmark model where the result is compared with a NAFEMS benchmark solution. Read More
