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 many structural dynamics applications, some components are stiff compared to the supporting structure. Such a stiff part will only contribute to the dynamic properties of the structure through its mass and moment of inertia. It is then possible to reduce the model size significantly ...

This model studies free and forced vibrations of a deep beam. The solution for eigenfrequency, frequency response and transient analysis are computed using a Timoshenko beam and compared with analytical results. Per saperne di più
The propagation of elastic waves in the ground after a seismic event is simulated using a 2D model. The effect of the ground surface topology on the wave propagation is illustrated when an ideal half-space is modified with the presence of a small mountain. The model is a variation of ...

As integrated circuit (IC) technology advances, with circuits becoming more powerful and compact, it is increasingly important to identify and prevent any cause of circuit failure. One particularly critical factor contributing to circuit failure is electromigration within the ... Per saperne di più
The eigenfrequencies of a rotating blade are studied in this benchmark. It shows how stress stiffening and the combined effect from stress stiffening and spin softening affects the fundamental eigenfrequency. High rotational speed in rotating machineries can result in centrifugal forces ... Per saperne di più
This example presents transient analysis of the wave propagation in rock mass caused by a short duration load on the surface. Such loads are typical during tunnel constructions and other excavations using blasting. The example shows the use of the Low-reflecting boundary conditions to ... Per saperne di più

A fuel cell stack operates at temperatures just below 100 °C, which means that it has to be heated at start-up. The fuel cell stack consists of unit cell of anode, membrane, and cathode connected in series through bipolar plates. This study presents a model that couples the thermal and ... Per saperne di più
Trusses are structural members that can only sustain axial forces, but no bending or torsion. In the following example you first build and solve a simple 2D truss model using the 2D Truss interface. Later on, you analyze a 3D variant of the same problem using the 3D Truss interface. This ... Per saperne di più
For slender structures, buckling is a catastrophic instability if the service load is above the critical limit. For such structures, it can be important to study the behavior of the structure beyond the critical buckling load, which is known as postbuckling analysis. Tracing the ... Per saperne di più
