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.
You can use the Method Editor in the Application Builder for creating methods that perform almost any type of modeling tasks, including geometry modeling. It is easy to miss the fact that methods can support recursion by having a method calling itself in a recursive loop. Here, we will ... Per saperne di più
Beam theories are well-developed for slender structures with homogeneous materials and isotropic cross-sections. The traditional beam theories do no apply to beams made of different materials in the cross-section. Therefore, a homogenization-based numerical model is needed to compute ... Per saperne di più
The sound distribution from a TV in a two-room apartment is computed. The simulation demonstrates the use of the Acoustic Diffusion Equation interface to get a quick and simple estimate of the local sound pressure level. For increased accuracy, an analytical expression for the direct ... Per saperne di più
A simple way to estimate the value of π is by using a pendulum, whose oscillation period can be measured and used to calculate an approximation. This simulation app is based on a model that uses the <em>Multibody Dynamics</em> interface to describe the motion of a simple ... Per saperne di più
The homogenized material properties of a composite are computed based on the temperature-dependent properties of matrix and fiber. The homogenized parameters are compared to the analytical values derived from the rule of mixtures. This is an extension of model https://www.comsol.com ... Per saperne di più
This model describes the corrosion of magnesium (Mg) alloys in physiological environments using a phase-field formulation. The approach couples Mg dissolution kinetics with ionic transport, enabling the transition from activation-controlled to diffusion-controlled regimes to be captured. ... Per saperne di più
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
This example demonstrates how to set up text files to use when preprocessing models that contain hundreds of parts. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Automate Model Preprocessing with the Application Builder". Per saperne di più
This tutorial shows how to model an arbitrary surface acoustic wave (SAW) delay line. The design parameters are arbitrary in the sense that the outputs are far from optimal from a practical standpoint. The aim is to show how a SAW device can be set up in the software: how to define the ... Per saperne di più
