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 tutorial example, the concepts of Component Mode Synthesis (CMS) are introduced through a simple solid model of a cantilever beam. Parts of the beam are reduced by the CMS technique. It is, furthermore, shown how CMS can be used to represent both the static and dynamic behavior ... Per saperne di più
In this example, the homogenized elastic and viscoelastic properties of a particulate composite are computed based on the individual properties of elastic particles embedded in a viscoelastic matrix. Periodic boundary conditions are applied to a unit cell of the particulate composite ... Per saperne di più
In this parameter optimization example, the mass of a bracket is minimized by changing the size and position of a number of geometrical objects. The requirements give limits both on the lowest natural frequency, and on the maximum stress in a static load case. This means that results ... Per saperne di più
The thermal stress in a layered plate is studied in this example. A plate consisting of two layers, a coating and a substrate layer, is stress and strain free at 800 degrees C. The temperature of the plate is reduced to 150 degrees C and thermal stresses are induced due to the difference ... Per saperne di più
Reflow soldering is an important process in IC packaging. In reflow soldering, the solder materials are melted to create joints between electrical components and the PCBs for structural and electrical connections. This model demonstrates the process of attaching chips to a PCB by reflow ... Per saperne di più
This example shows how to model prestressed bolts. The bolt geometry is taken from the Part Libraries. For comparison, one of the bolts is modeled using a thread contact formulation, whereas the other bolt is connected to the bolt hole by a pure continuity condition. The reduced ... Per saperne di più
These examples demonstrate how to generate randomized geometric surfaces. Note that there is now also an add-in covering random surface functionality for planar surfaces. The COMSOL Multiphysics® software provides a powerful set of built-in functions and operators, such as ... Per saperne di più
Liquid or gas acoustics coupled to structural objects such as membranes, plates or solids are important applications in many engineering fields. This model is a general demonstration of an acoustic fluid phenomenon in 3D that is coupled to a solid object. The walls of the solid object ... Per saperne di più
This is a tutorial example, showing how to work with pretensioned bolts. Various aspects of bolt modeling are explored: Modeling bolts as solids or by beams Connections of beams to solid components Bolts ended by nuts or by internal threads in the attached component Import of bolt and ...

In this conceptual example, the soft impact between two elastic rings is modeled using the Solid Mechanics interface. One of the rings is given an initial velocity to initiate the impact event. Both rings are unconstrained and not subjected to any external forces. Contact is modeled ... Per saperne di più
