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.
Squeeze film dampers are components that provide additional damping to rotating machines. To simplify the modeling of a rotor assembly, squeeze film dampers are modeled in terms of their damping coefficients which are a functions of the journal location in the damper. This model computes ... Per saperne di più
In this example, a rotor supported on two hydrodynamic bearings is analyzed. An eccentric disk located between the two bearings causes the rotor to whirl. One of the bearings is misaligned with the axis of the rotor. The Beam Rotor with Hydrodynamic Bearing interface in the ... Per saperne di più
This a continuation of the permanent magnet motor model available here . In this model, an heat transfer analysis has been performed to compute the temperature rise for various stator current and rotor speed. A detailed analysis on torque, and losses in iron and copper have then been ... Per saperne di più
Full scale, time dependent model of an offshore oil platform jacket utilizing sacrificial anodes, coating breakdown and calcareous deposits on steel surfaces. The tutorial aims to meet some of the common questions for simulations in the oil and gas industry. This of course applies to ... Per saperne di più
Permanent magnet bearings are used in turbomachinery, pumps, motors, generators, and flywheel energy storage systems, to mention a few application areas; contactless operation, low maintenance, and the ability to operate without lubrication are some key benefits compared to conventional ...

Walking instability, due to non-uniform distribution of clothes, is a common problem in lightweight portable washing machines. This problem is more severe in horizontal-axis washing machines, which are more popular because of their high efficiency in spite of high manufacturing cost. ... Per saperne di più
Vibration and noise in washing machines, due to the non-uniform distribution of clothes in the barrel, is a common problem worth studying and optimizing for. This model simulates a multibody dynamics model of a horizontal-axis portable washing machine. An eigenfrequency analysis is ... Per saperne di più
This is an example of a model of an induction motor in which the eddy currents are induced in the rotor by the time harmonic currents on the stator windings and the rotation of the rotor. In this example, we analyze the induction motor in 2D using the transient solver in the Rotating ... Per saperne di più
This single-phase induction motor model is used to compare with Testing Electromagnetic Analysis Method (TEAM) workshop problem 30. The Magnetic Fields physics interface is used to model the motor in the frequency domain at 60 Hz. The Velocity (Lorentz Term) feature is used to model the ... Per saperne di più
Switched reluctance motors work on the principle of reluctance torque. The stator and rotor will interact to minimize the reluctance for the flux path. This application simulates the behavior of the motor when the stator winding is excited with a step voltage and when the rotor is at a ... Per saperne di più
