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 capacitive micromachined ultrasonic transducer (CMUT) is a micro-scale receiver that converts ultrasound to electrical signal for high-resolution imaging application. This CMUT design has optimized force-displacement characteristics for increased transduction efficiency. Central to the ... Read More
The contact angle of a two-fluid interface with a solid surface is determined by the balance of the forces at the contact point. In electrowetting the balance of forces at the contact point is modified by the application of a voltage between a conducting fluid and the solid surface. In ... Read More
This introduction model creates a simple model of the magnetostatics problem with a wire of infinite length carrying current, which is commonly found in textbooks. Since there is an analytical solution to this problem, the model can be used to compare theory with numerical results from ... Read More
In this example, the transient response of a shallow foundation resting on an unsaturated soil stratum is investigated. The changes in pore suction due to water infiltration and evaporation are analyzed using the Extended Barcelona Basic soil model. The results show how the deformation ... Read More
In this model, sound created by a vibrating piston radiates through a baffled pipe. The impedance is measured and then used in an impedance boundary condition that replaces the surrounding air domain. This technique can be employed to reduce solution time and memory usage for large ... Read More
In this example, a lumped model of a vehicle suspension system having 11 degrees of freedom is analyzed. The Mass, Spring, and Damper nodes of the Lumped Mechanical System interface are used to model the wheels, including suspension system as well as the seats with a passenger. The ... Read More
Delamination or the separation of layers is a common failure mode in laminated composite materials. Various factors, including loading, defects in the material, and environmental conditions can trigger the initiation and propagation of layer separation. This leads to degraded structural ...

The External Material functionality makes it possible to program your own material models for cases when the built-in material models are not sufficient. For structural mechanics, you have the possibility to either completely define the material model in a domain, or to add an inelastic ... Read More
This tutorial demonstrates how an electrical circuit model of a MEMS resonator can be derived using the Parameter Estimation feature. The model is a modified Butterworth-Van Dyke circuit created using the Electrical Circuit interface and represents a Thin-Film Bulk Acoustic Resonator ... Read More
This model deals with electrohydrodynamics (EHD), where a charge separation on the phase boundary between a liquid and air involves the formation of a charged layer. This charged layer allows for a net force to be induced at the interphase when a large electric field is applied. The ... Read More
