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 analyzes the frequency response of a fuel tank partially filled with fluid. The tank is submitted to a vertical acceleration. Two modeling methods are considered to represent the fluid: a traditional method of smearing the mass of the fluid through the wetted surface of the ... Read More
In this example, two model for brittle damage are used to evaluate the fracture of a notched concrete beam subjected to three point bending. The results are compared with experimental data. Read More
This example presents transient analysis of the wave propagation in rock mass caused by a short duration load on the surface. Such loads are typical during tunnel constructions and other excavations using blasting. The example shows the use of the Low-reflecting boundary conditions to ... Read More
Electrochemical glucose sensors use amperometric methods to measure the concentration of glucose in a sample. This example models the diffusion of glucose and ferri/ferrocyanide redox mediators in a unit cell of electrolyte above an interdigitated electrode. The sensor gives a linear ... Read More
When a conductive solid material moves through a static magnetic field, an eddy current is induced. The current that flows through the conductor, which is itself moving through the magnetic field, induces a Lorentz force back on the solid. Therefore, a conductive solid that is vibrating ...

This example considers the turbulent flow of an oil-water suspension through an orifice. The oil droplets are broken up into smaller droplets by the turbulent stresses as the suspension passes through the orifice. The aim of this model is to track the distribution of droplet sizes. The ... Read More
This model simulates atmospheric galvanic corrosion of a busbar, which includes a copper flange, an aluminum alloy flange in contact with a zinc nut and bolt. The Secondary Current Distribution interface is used to solve for the electric potential in electrode domain and Current ... Read More
This model represents a test case of a flow in an elastic tube which is present in several applications. This specific case models viscoelastic flow and represents steady flow in a channel in which part of the upper wall is replaced by an elastic plate subjected to an external pressure. ... 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 example describes the operation of a drug delivery system that supplies a variable concentration of a water soluble drug. A droplet with a fixed volume of water travels down a capillary tube at a constant velocity. Part of the capillary wall consists of a permeable membrane ... Read More
