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.
Chemical vapor deposition (CVD) is a process often used in the semiconductor industry to grow layers of high-purity solid material on top of a wafer substrate. CVD is achieved using many different techniques and across a range of pressures from atmospheric to ultrahigh vacuum (UHV/CVD). ... Per saperne di più
Creep is an inelastic time-dependent deformation which occurs when a material is subjected to stress at sufficiently high temperature, say 40% of the melting point or more. Experimental creep data (using constant stress and temperature) often display three different types of behavior ... Per saperne di più
We present the results from a comparison of the level set, phase field, and moving mesh methods for modeling free liquid surfaces in the COMSOL Multiphysics® software. The comparison is carried out using an example problem. The example studies the formation of surface waves ... Per saperne di più
This example shows how the mixing capability of a stirred vessel can be evaluated. To efficiently reach the steady operational conditions the turbulent flow is solved for using a frozen rotor analysis, and a following time dependent simulation. When a quasi-steady flow field has ... Per saperne di più
Microlaboratories for biochemical applications often require rapid mixing of different fluid streams. At the microscale, flow is usually highly ordered laminar flow, and the lack of turbulence makes diffusion the primary mechanism for mixing. While diffusional mixing of small ... Per saperne di più
SMA connectors are popularly used on printed circuit boards (PCB) for testing. This model shows how to excite an SMA connector on a microwave substrate and how to terminate a grounded coplanar waveguide (GCPW) with 50 ohm using a lumped port and an air-bridge. Per saperne di più
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
This benchmark model simulates three different heterojunction configurations under forward and reverse bias. It shows the difference in using the continuous quasi-Fermi level formulation versus the thermionic emission formulation for the charge transfer across the heterojunction. The ... Per saperne di più
This benchmark model simulates a GaAs nanowire using the self-consistent Schrödinger-Poisson theory to compute the electron density and the confining potential profiles. The predefined Schrödinger-Poisson multiphysics coupling feature is combined with the dedicated Schrödinger-Poisson ... Per saperne di più
This type is one of the most popular laser cavities. In particular, it is often used for the Ti-doped sapphire femto-second laser. The stability of the laser cavity is analyzed by releasing a ray inside the cavity and is traced for a predefined time period that is sufficiently long. ... Per saperne di più
