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.
Bearings are used in machines to reduce the friction between moving parts and thereby smooth their relative motion. Rolling element bearings are one of the most widely used bearings, where rolling elements or rollers are used to support the load. These rollers can be of different shapes; ... Per saperne di più
In this example, a simple ultraviolet (UV) water purification reactor is modeled using a combination of ray tracing, computational fluid dynamics, and Lagrangian particle tracking. First, the volumetric fluence rate is accumulated along rays released from the surface of the UV lamp using ... Per saperne di più
The Keck Telescope is a 10 meter diameter telescope with a Ritchey-Chretien optical design. It is noted for being one of the first large optical telescopes to utilize a lightweight segmented primary mirror. This tutorial demonstrates how to use built-in polygonal mirrors from the COMSOL ...

This example demonstrates how to import a bitmap which can be used to simulate an image using ray tracing. The example is based on the Double Gauss Lens tutorial from the Ray Optics Module Application Library. The first study has been modified so that the Spot Diagram "auto-focus" tool ...

Wastewater treatment is a several-step process for removing contaminants. Firstly, large, solid particles are removed through sedimentation, flotation, and filtration. And then in a second step, biological treatment causes the smaller particles to aggregate, forming so called flocs. ... Per saperne di più
In this benchmark model, solid particles are released in a fully developed turbulent channel flow. The particles are subjected to a drag force that includes contributions from the fluid turbulence, implemented using a Continuous Random Walk (CRW) model. Because the turbulence in the ...

This example simulates the separation of particles based on the size in a microchannel using the method of pinched flow fractionation. The microdevice has two inlets and multiple outlets where the velocity field of liquid flow is calculated using the Laminar Flow interface. Then the ... Per saperne di più
Dielectrophoresis (DEP) occurs when a force is exerted on a dielectric particle as it is subjected to a nonuniform electric field. DEP has many applications in the field of biomedical devices used for biosensors, diagnostics, particle manipulation and filtration (sorting), particle ... Per saperne di più
This example simulates particles in a range of sizes that move through different levels of a cascade impactor. A cascade impactor is an inertial particle separation device consisting of multiple levels separated by collecting plates and nozzles. Particle-laden air enters from the top ... Per saperne di più
This tutorial shows how to use the Surface-to-Surface Radiation interface to simulate radiative heat transfer with radiation between diffuse emitters and diffuse-and-specular reflectors. This model is separated in two parts. The first part focuses on a validation test for the radiative ... Per saperne di più
