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 multibody dynamics model of a simple counterweight trebuchet, a parametric sweep is used to study throwing distance as function of the sling length. For more details on performing a multibody analysis of a counterweight trebuchet, see this blog post: What Is the Physics Behind a ... 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
Mechanical precession prevents bicycle pedals from falling off. The model captures this effect using a multibody dynamics simulation together with a contact analysis. A friction coefficient is associated with the contact in order for the model to capture the effect. Per saperne di più
A highly simplified pedestrian bridge is for simplicity imagined to consists of a concrete slab on supported by three I-beams. The design is to be evaluated for peak acceleration due to walking. The model analyzes uncertainty in peak acceleration due to some material damping properties ... Per saperne di più
The electrodes of a lithium-ion battery are porous, consisting of an active solid material, a binder, and pores filled with liquid electrolyte. If a force is applied on the porous layers of a battery, this will affect the volume fraction of the electrolyte-filled pores in the electrodes, ... Per saperne di più
This is a demo model to show how to model connections in a mechanical system using Multibody Dynamics interface. In this model, pantograph mechanism is modeled. The purpose of this mechanism is to produce an identical, either enlarged or miniaturized, copy of an existing drawing. Per saperne di più
This model uses the Granular Flow and Membrane interfaces to simulate the packing of spherical grains in a flexible container, a procedure often found in the processing industry. In this example, grains are packed into a cubic container constructed of a thin polymer fabric. Two packing ... Per saperne di più
This example shows how to model isotropic volumetric growth and atrophy of soft biological tissues. The artery is represented by a cylinder that is stretched and compressed due to an applied axial load. As a result, the tissue undergoes growth and atrophy. 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
This parametrized model can be used to simulate the hopping hoop problem. A rolling ring with a point mass on the perimeter can, under certain conditions, jump up from the surface on which it is rolling. A more detailed description of this model can be found in the blog post "The ... Per saperne di più
