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 small building block of integrated photonics, i.e., a Silicon-on-Insulator taper, is considered. For a larger system design, it might be useful to determine the phase delay such a device introduces. Here, we showcase the layout needed to do it in COMSOL, including a proper Port ...

Solving very large pressure acoustics models in the frequency domain can be challenging. Several iterative solver suggestions exist for the default physics setups and the default quadratic Lagrange discretization. For very large models it can be advantageous to switch from quadratic to ... Per saperne di più
Many robot vacuum cleaners nowadays are equipped with lidar for spatial mapping in order to design an optimal cleaning path and navigate in a room without bumping into obstacles. This model simulates the lidar of a robot vacuum cleaner and how it maps out the shape of the room using ... Per saperne di più
In electrosurgery, high-power AC current from a probe is driven into tissue in order to cut and coagulate it. The current causes rapid Joule heating near the tip, and as temperatures reach 100°C, water and blood vaporize and the tissue desiccates, enabling cutting or sealing. This ... Per saperne di più
This model showcases a nail penetration experiment into a layered battery. It couples the Solid Mechanics, Lithium-Ion Battery, and Heat Transfer interfaces. A nail is punched into a sandwiched battery consisting of two electrodes and a separator. As soon as the nail connects both ... Per saperne di più
This model analyzes negative corona formation in a point-to-plane configuration driven by high applied voltages. The resulting I–V characteristics align well with experimental observations documented in the literature. The goal here is to capture the steady electrical characteristics ... Per saperne di più
This model is used to demonstrate the solution to a classic brainteaser in electromagnetics. A long loop of wire is connected to a source and a receiver, which are placed 1 meter apart. The objective of the model is to compute how long it takes for the receiver to sense when the source ... Per saperne di più
This model simulates a beam of light being split into components of different frequencies when passing through a medium where the refractive index depends on frequency. COMSOL-wise, the model showcases two important technical aspects: A user-defined implementation of the frequency ... Per saperne di più
This model examines the behavior of a positive corona formed between concentric cylindrical conductors exposed to high applied voltages. The predicted current–voltage response closely matches the measurements. Rather than reproducing individual positive glow corona bursts, the setup ... Per saperne di più
An interesting question was raised in the 1950s by the mathematician Ernst Straus that, in an arbitrarily shaped empty room with side walls made of perfect mirrors, will a point light source always illuminate the whole room? This question was answered by the Nobel Prize-winning ... Per saperne di più
