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.
A tapered slot antenna, also known as a Vivaldi antenna, is useful for wide band applications. Here, an exponential function is used for the taper profile. The objective of this model is to compute the far-field pattern and to compute the impedance of the structure. Good matching is ... Per saperne di più
When modeling the propagation of charged particle beams at high currents, the space charge force generated by the beam significantly affects the trajectories of the charged particles. Perturbations to these trajectories, in turn, affect the space charge distribution. The Charged ... Per saperne di più
This model demonstrates how the Free Shape Boundary feature can be used to perform shape optimization on a design found with topology optimization. The model uses the same objective and constraint as the original, which results in a slightly higher stiffness for the same mass. Per saperne di più
This model is an introduction to defining and verifying a satellite orbit, and computing the solar, albedo, and Earth infrared thermal loads. A 1U CubeSat is in a circular orbit at 400km altitude, inclination of 50°, and longitude of ascending node of 0°. The satellite is rotating slowly ... Per saperne di più
This example is an extension of a model used to study the vibration and noise in a 5-speed synchromesh gearbox in a manual transmission vehicle. In this version of the model, a detailed representation of a roller bearing is used instead of hinge joints with elastic stiffness. First, the ... Per saperne di più
Layered shell elements, which are used for modeling composite shells, often connected to solid and shell elements in cladding or side-by-side configuration to represent a realistic structure. For such applications, it becomes important to connect layered shell element correctly and ... Per saperne di più
Planar photonic waveguides in silica (SiO2) have great potential for use in wavelength routing applications. The major problem with this type of waveguide is birefringence. Anisotropic refractive indices result in fundamental mode splitting and pulse broadening. The goal is to minimize ... Per saperne di più
This model uses the Reacting Flow multiphysics interface to simulate a methane steam reformer. The model accounts for the interactions between the chemical reactions, the transport of species, the fluid flow, and the heat transfer in a porous medium. Per saperne di più
This example simulates the underground storage of CO2 in a part of the Johansen formation off the coast of Norway. The CO2 is injected using an injection well at a rate of 15 kg/s over a period of 25 years, after which the well is closed. The model is used to compute the spreading of CO2 ... Per saperne di più
Predicting the noise radiation from a dynamic system gives designers insight into the behavior of moving mechanisms early in the design process. For example, consider a gearbox in which the change in the gear mesh stiffness causes vibrations. These vibrations are transmitted to the ... Per saperne di più
