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 model, a rotor with permanent magnets and a nonlinear magnetic material rotates within a stator of the same magnetic material. The generated voltage in windings around the stator is calculated as a function of time. COMSOL Multiphysics models the rotation with assemblies and ... Per saperne di più
This model shows how to control the position of the base of an inverted pendulum to keep it vertical. The control is performed using a PID controller in Simulink®. The position of the base is constrained within specified limits, and an external force is applied at the base to keep it ... Per saperne di più
Loudspeaker design is a challenging task, where the design objective is to achieve better sound quality without violating manufacturing and operational constraints. The quality of sound depends on many parameters; one of them is the ability to control, damp, and shift the diaphragm ... Per saperne di più
This example demonstrate two-phase flow in a porous medium which contains a low permeable lens. The heavier phase infiltrates the porous medium, so the low permeable lens is infiltrated only when a critical saturation at the outside is reached. Per saperne di più
This model reproduces the NiCd battery model and the results presented in De Vidts' and White's paper from 1995. Ref: P. De Vidts, R. E. White, “Mathematical Modeling of a Nickel-Cadmium Cell: Proton Diffusion in the Nickel Electrode”, J. Electrochem. Soc, Vol. 142, No. 5, May 1995. Per saperne di più
In this first half of a two-part example, a 2D model of a trench-gate IGBT is built, which will be extended to 3D in the second half. In general, it is the most efficient to start with a 2D model to make sure everything works as expected, before extending it to 3D. The Caughey&ndash ... Per saperne di più
The first stop for polluted water entering a water work is normally a large tank, where large particles are left to settle. Generally, gravity settling is an economical method of separating particles. If the fluid in the tank is moving at a controlled low velocity, the particles can be ... 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
In this tutorial, the heat and mass transport equations are coupled to laminar flow in order to model exothermic reactions in a parallel plate reactor. It exemplifies how you can use COMSOL Multiphysics to systematically set up and solve increasingly sophisticated models using predefined ... Per saperne di più
Fluid dampers are used in military devices for shock isolation and in civil structures for suppressing earthquake-induced shaking and wind-induced vibrations, among many other applications. Fluid dampers work by dissipating the mechanical energy into heat. This model shows the phenomenon ... Per saperne di più
