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.
In this model, a turbocharger supported on two floating ring bearings is studied. The film forces on the ring cause it to rotate within the bearing. In steady state, the ring rotates at a constant angular speed and the torque on the ring due to the inner and outer films are balanced. ... Per saperne di più
This model demonstrates the use of the Heat and Moisture Flow features for the simulation of superheated steam drying of a wood particle. A nonequilibrium formulation is used to compute the transport of the liquid water and vapor phases in the wood particle. Reference: Le, K. H., ... 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
Nucleate boiling occurs when a liquid is heated by a source hotter than the saturated fluid temperature but with a heat flux below the critical heat flux. In this regime, high heat flux are possible due to the evaporation of the liquid. This model aims to demonstrate the calculation of ... Per saperne di più
A catalyst particle with a hypothetical microstructure is described in detail. The heterogeneous description is approximated in a second model with a homogeneous particle and the results from the two approaches are compared.

Modeling curing is important in a wide variety of applications such as for devices utilizing polymer materials, rubber materials, plastics, and concrete. Curing is usually an exothermic reaction. In the current example, curing of butyl rubber is studied in a 3D mold for an automotive ... Per saperne di più
This example minimizes the mass of a bracket that is synchronized from SOLIDWORKS® via the LiveLink™ interface. There are limits both for the lowest natural frequency, and for the maximum stress in a static load case. The size and position for a number of geometrical features ... Per saperne di più
This model demonstrates how a nonlinear equation system can be setup to solve for the eigenfrequencies of a symmetric laser cavity. The model uses the bidirectional formulation of the Electromagnetic Waves, Beam Envelopes physics interface. The computed eigenfrequencies are verified with ... Per saperne di più
In a MESFET, the gate forms a rectifying junction that controls the opening of the channel by varying the depletion width of the junction. In this model we simulate the response of a n-doped GaAs MESFET to different drain and gate voltages. For a n-doped material the electron ... Per saperne di più
A steel ball is pressed down against a rubber membrane. When the contact pressure exceeds a certain value, the two parts start sticking together. When the ball is retracted, the membrane is pulled upwards in the bonded region. During the retraction, the bond is partially broken. This ... Per saperne di più
