La Galleria delle Applicazioni raccoglie un'ampia varietà di tutorial e di app dimostrative realizzati con COMSOL Multiphysics in diversi ambiti applicativi, inclusi quelli elettrico, meccanico, fluidico e chimico. E' possibile scaricare i file dei modelli e delle app demo pronti all'uso e le istruzioni step-by-step per costruirli, e utilizzarli come punto di partenza per le proprie simulazioni.
Lo strumento di Ricerca Rapida permette di trovare i modelli che si riferiscono alla propria area di interesse.
Si noti che molti degli esempi qui presentati sono accessibili anche tramite le Librerie delle Applicazioni incorporate nel software COMSOL Multiphysics® e disponibili dal menu File.
Light collimation or focusing is a basic task often needed when working with lasers in the lab where singlets are used due to their simplicity. If a plano-convex lens is used for the task, there is a correct lens orientation that minimizes aberrations. A useful rule-of-thumb is to ... Per saperne di più
Uncertainty quantification is used to study the effect of manufacturing variation on the performance of a 2D solidly mounted resonator (2D SMR). This tutorial shows how the resonant frequency is affected by thickness variations of the piezoelectric layer and the Bragg reflector layers. ... Per saperne di più
In his example, the lowest natural frequency of a 3D bracket are maximized using shape optimization. Per saperne di più
A paraboloidal dish can concentrate solar energy onto a target (receiver), resulting in very high local heat fluxes. This can be used to generate steam, which can be used to power a generator, or hydrogen, which can be used directly as a fuel source. In this model, the heat flux arriving ... Per saperne di più
Surface plasmon-based circuits are being used in applications such as plasmonic chips, light generation, and nanolithography. The Plasmonic Wire Grating Analyzer application computes the coefficients of refraction, specular reflection, and first-order diffraction as functions of the ... Per saperne di più
KOH(aq), an alkali metal hydroxide solution, is widely used in anisotropic wet etching technology and is one of the most commonly utilized solutions for micromachining silicon wafers. Anisotropic etching refers to a process where the etching rate varies in different directions, primarily ... Per saperne di più
This example shows a 2D plane stress model of a thin tapered cantilever. Different boundary and load scenarios are examined. It is demonstrated how to apply and how to evaluate different load and constraint groups. Resulting stresses are compared to NAFEMS benchmark values and they are ... Per saperne di più
Microstrip filters can be fabricated directly on a printed circuit board (PCB) with a microstrip line going from the input to the output. Along the microstrip line there are a number of stubs of certain lengths and widths. The design of the filter involves choosing the impedance of the ... Per saperne di più
This example models the deposition of an inductor coil in 3D. The geometry includes the extrusion of the deposition pattern into an isolating photoresist mask, and a diffusion layer on top of the photoresist. The mass transfer of copper ions in the electrolyte has a major impact on the ... Per saperne di più
This model exemplifies how the rate of steel corrosion in an oil platform increases over time due to build-up of a resistive film on the sacrificial anodes, formed by reaction products. The model also includes secondary current distribution electrode kinetics on the protected steel ... Per saperne di più
