In diesem Beispiel wird der Sprödbruch einer gelochten Platte mit einer Kerbe mithilfe eines Phasenfeld-Schadensmodells modelliert. Die Geometrie der Platte ist so eingestellt, dass ein Mischbruch induziert wird, wobei die Abmessungen und Materialeigenschaften aus experimentellen Daten ... Mehr lesen
A radio frequency quadrupole ion trap utilizes a radio frequency quadrupole (RFQ) in order to trap an ion beam. A continuous high energy ion beam is first cooled and converted into a spatially confined bunch, which can then be released with minimal heating of the beam. The device is also ... Mehr lesen
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 ... Mehr lesen
A Butler matrix is a passive beamforming feed network. It is a cost-effective feed network for phased array antennas because the circuit can be fabricated in the form of microstrip lines and is a viable solution for performing beam scanning without deploying expensive active devices. ... Mehr lesen
This example is a model of a continuous casting process. Liquid metal is poured into a mold of uniform cross section. The outside of the mold is cooled and the metal solidifies as it flows through. When the metal leaves the mold, it is completely solidified on the outside, but still ... Mehr lesen
This model shows how to compute an array of borehole heat exchangers (BHEs) for shallow geothermal energy production. The BHEs are simplified as line heat sinks with a uniform heat extraction rate. The array is embedded into a layered subsurface model with groundwater flow in one of the ... Mehr lesen
A fuel cell unit cell is modeled using the full Butler-Volmer expression for the anodic and cathodic charge transfer reactions. The anodic and cathodic overpotentials depend on the local ionic and electronic potentials, which are obtained from the charge balance equations for ionic and ... Mehr lesen
In a polymer electrolyte membrane water electrolyzer cell, hydrogen and oxygen gas is produced by electrolysis. The hydrogen and oxygen compartments are separated by a polymer membrane, that also acts as electrolyte. This introductory tutorial computes the ohmic and activation losses in ... Mehr lesen
This is a demonstration of how to use the thermodynamics functionality in the COMSOL Multiphysics® software to make flash calculations. A flash calculation is an equilibrium calculation of a system where several species and phases are present at the same time. The system in ... Mehr lesen
This three-phase induction motor model is used to compare with Testing Electromagnetic Analysis Method (TEAM) workshop problem 30. The Magnetic Fields physics interface is used to model the motor in the frequency domain at 60 Hz. The Velocity (Lorentz Term) feature is used to model the ... Mehr lesen
