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 model serves the purpose of validation and verification of the Linear Elastic Material, Layered model in the Shell interface. In COMSOL Multiphysics, composites are analyzed either based on Layerwise 3D elasticity theory through the Layered Shell interface or based on FSDT-ESL ... Read More
This benchmark model simulates three different heterojunction configurations under forward and reverse bias. It shows the difference in using the continuous quasi-Fermi level formulation versus the thermionic emission formulation for the charge transfer across the heterojunction. The ... Read More
The Cathodic Protection Designer application is an example of how an application can be used to simplify the simulation process by featuring a way to import a generic CAD file with certain requirements. Using this app, the user can select each part of the geometry and set boundary ... Read More
In this example, a benchmark problem in dynamic fracture of brittle materials is analyzed using the AT1 phase-field damage model. An instantaneous tensile load is applied to a planar tension specimen with a pre-existing crack. Initially, the crack propagates perpendicular to the loading ... Read More
This model shows how shape optimization can be used design the coils of an ICP reactor to obtain plasma uniformity. The reactor in study is a planar ICP with the coils distributed along the radial direction. The Optimization study step is used to find the best coil placement so that the ... Read More
This is a model of a simple photoacoustic (or optoacoustic) resonator. A pulsating laser heats a gas causing expansion and contraction and thus creates pressure waves. Such devices are used as sensors for measuring material parameters of the gas inside the resonator. The resonance ... Read More
This is a model of an RF waveguide bend with a dielectric block inside. There are electromagnetic losses in the block as well as on the waveguide walls which cause the assembly to heat up over time. The material properties of the block are functions of temperature. The transient thermal ... Read More
This is a template base model containing the physics, geometry and mesh of a lithium-ion battery, defined in 1D. The model makes use of four lithiation parameters which are used to define the relative balancing of the negative and positive electrodes, as well as global cell state of ... Read More
An established method for benchmarking the atmospheric corrosion resistance of materials is the use of accelerated corrosion tests (ACT) performed in climate chambers. The main purpose of the ACTs is to make reliable and fast predictions of the long time behavior. The tests expose ... Read More
The model utilizes a dedicated mesh refinement study, Frequency Domain RF Adaptive Mesh, which dynamically refines the mesh in the region of interest. For the Application Library model Microstrip Patch Antenna, it increases the mesh resolution around areas with high field variations. The ... Read More
