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.
The noise emitted from an electrical machine can have many sources. In this example, acoustic noise from vibrations created by magnetic force variation is studied. Such noise is often audible at twice the excitation frequency but can also occur at higher frequencies or harmonics of the ... Per saperne di più
High Cycle Fatigue (HCF) of a spoke in a wheel rim is studied. As the wheel rotates, the stress histories in the structure will become nonproportional. The risk of fatigue is evaluated using the Findley criterion. Per saperne di più
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
Piezoelectric devices are widely used as sources to generate sound waves or receivers to detect acoustic signals. In applications such as ultrasound imaging and nondestructive testing, the same transducer can be used as a transmitter to send a source signal and receiver to detect ... Per saperne di più
This example benchmarks a NAFEMS validation model of a friction contact problem with an elastoplastic material model. A thin metal sheet is forced into a die by a punch. Both the compressing displacement and the release of the punch are modeled in order to compute the forming angle (at ... Per saperne di più
This model is of the P.57 Type 4.3 Full-band Ear Simulator. The model includes the geometry of the ear canal as well as the pinna defined in the ITU-T P.57 standard. The model also includes interpolation data for an ear drum impedance ensuring correct acoustic properties of the ear. The ... Per saperne di più
This tutorial model shows how to import a 3D scanned geometry of a human head and torso and compute the head related transfer function (HRTF). The scan is imported as a .stl file and converted into a COMSOL geometry. The HRTF is computed using the reciprocity principle, locating the ... Per saperne di più
When simulations are involved in the development of mobile devices, consumer electronics, hearing aids, or headsets, it is necessary to consider how the transducers interact with the rest of the system. Here, we show an analysis of the interaction between a vibration isolation mounting ... Per saperne di più
An AC contactor is a particular type of magnetic switch device, which is activated by a primary coil fed by an alternating current. Unlike DC switches, such devices can suffer from a tendency to reopen when the AC current crosses zero. The addition of a shading coil that supports ... Per saperne di più
Many engineering structures consist of thin and slender components, where a full solid model will result in extremely many small elements. For such structures, it is much more efficient to use shell or beam elements. In this tutorial and verification model, it is shown how to connect ... Per saperne di più
