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.
This a continuation of the permanent magnet motor model available here . In this model, an heat transfer analysis has been performed to compute the temperature rise for various stator current and rotor speed. A detailed analysis on torque, and losses in iron and copper have then been ... Per saperne di più
Tutorial example of the RF heating of passive conductive implants (rod and screws) inserted in three vertebrae during MRI. The RF fields are locally enhanced in the proximity of a passive conductive implant resulting in the heating of the portion of tissue facing the implant's surface. Per saperne di più
The level set method is well suited for problems with moving boundaries in which the geometry’s topology changes with time. A bubble of oil that travels up through water and finally merges with oil at the top causes this kind of topology change. For problems where the topology is ... Per saperne di più
This example exemplifies how to model the switching between current and voltage excitations in Terminal boundary conditions. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Control Current and Voltage Sources with the AC/DC Module". Per saperne di più
This example shows how to model Lithium diffusion in a silicon electrode that swells. The model shows how swelling-induced plastic deformation can increase the maximum state of charge (SOC). Per saperne di più
This model demonstrates how to use the Interior Contact feature to model the contact pressure at a bolted joint connecting two copper busbars. The AC current flowing through the assembly is induced to flow close to the outside boundaries of the conductors, but the contact resistance is ... Per saperne di più
This Application Gallery entry demonstrates how Far-Field radiation can be calculated when a substrate is present. Two approaches are demonstrated. A simplified form that works for two homogeneous domains, and a general approach that can handle multiple, inhomogeneous layers. This ... Per saperne di più
Light Detection And Ranging (LIDAR) is used extensively in self-driving cars to perform the quantitative ranging of the surroundings obstacles. The LIDAR system consists of a laser beam which gets broadened using a MEMS mirror with a particular horizontal and vertical field of view ... Per saperne di più
Electrode balancing is an important factor in the design of lithium-ion batteries. In this model, use the experimental open-circuit voltage of a cell and some basic assumptions, followed by an optimization solver, to find a proper electrode balancing. Get more details in this ... Per saperne di più
In this model, two concave mirrors are placed at a distance and a ray is released from a point inside the cavity. Then the ray is traced for a predefined time period that is sufficiently long. Ray tracing continues until the predefined computation time has passed if the laser cavity is ... Per saperne di più
