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.
This example demonstrates how to model coupled flow, heat transfer, and structural deformation and stress in a pipeline network. Gravity loads from the pipe and fluid are also taken into account. Per saperne di più
This model shows how to use simulations to predict power numbers with Power Law fluids in a mixer. It simulates the behavior of flow in a flat bottom tank with a single four-blade pitched impeller. The flow was modeled as laminar and the frozen rotor approach was used to solve the ... Per saperne di più
This tutorial example shows how to perform a random vibration analysis of a structure using power spectral density (PSD). The computations are based on the modal reduced order model (ROM). Per saperne di più
Different types of elements can be used for modeling a rotor, depending on the level of complexity and the type of the system being modeled. The modeling steps and representation of the results will vary with the type of idealization. In this tutorial model, an eigenfrequency analysis is ... Per saperne di più
This app demonstrates the following: Multiple tabs in the ribbon Geometry parts and parameterized geometries Parts and cumulative selections can be used to automatically set domain and boundary settings in the embedded model Adding or removing geometry parts with different geometrical ...

In this set of eight tutorial models and associated documentation, you can investigate the resistive, capacitive, inductive, and thermal properties of a standard three-core lead-sheathed XLPE HVAC submarine cable with twisted magnetic armor (500 mm2, 220 kV). The series includes a 2D, 2D ... Per saperne di più
A tube connection consisting of a flange with eight prestressed bolts is subjected to a set of loads: an internal pressure, an axial force, and an external bending moment. Due to two symmetry planes, it is sufficient to only consider one quarter of the full geometry. The study ... Per saperne di più
This example is an extension of a model used to study the vibration and noise in a 5-speed synchromesh gearbox in a manual transmission vehicle. In this version of the model, a detailed representation of a roller bearing is used instead of hinge joints with elastic stiffness. First, the ... Per saperne di più
A homopolar generator is composed of an electrically conductive rotating disc placed in a uniform magnetic field that is perpendicular to the plane of rotation. The motion of the conductor through the static magnetic field induces Lorentz currents in the disc. By connecting the outside ... Per saperne di più
In this tutorial model, you will see how to set up an eigenfrequency analysis of a rotor with multiple disks and bearings. The example illustrates how to use Campbell and stability diagrams to identify the critical speeds and the stability threshold. The rotor is modeled using the Beam ... Per saperne di più
