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 shows how to set up multiple sandwiched thin layers with different thermal conductivities in two different ways. First, the composite is modeled as a 3D object. In the second approach the Thin Layer boundary condition with the thermally thick option is used to avoid ... Per saperne di più
This tutorial model uses a heat sink geometry from the Part Library. The tutorial shows different approaches to heat transfer modeling when studying the cooling of an electronic chip. In the first part, only the solid parts are modeled, while the convective airflow is modeled using ... Per saperne di più
This example simulates electroplating of a printed circuit board (PCB) in 3D using the Secondary Current Distribution interface. In order to achieve thickness uniformity across the PCB, a dummy pattern is included in the design, along with an aperture in the electroplating bath. Per saperne di più
This example models a solid oxide electrolyzer cell wherein water vapor is reduced to form hydrogen gas on the cathode, and oxygen gas is evolved on the anode. The current distribution in the cell is coupled to the cathode mass transfer of hydrogen and water and momentum transport. Two ... Per saperne di più
This model uses the Optimization interface to solve the inverse problem for determining the spatially variable hydraulic conductivity on a discretized quadratic grid from a number of aquifer pump tests. Because the number of observations is smaller than the number of unknown parameters, ... Per saperne di più
A steel billet is quenched in oil from its austenitic state. A 2D axisymmetric model is used to simulate the coupled problem of austenite decomposition, heat transfer, and solid mechanics. During the quenching process, the austenite decomposes into a combination of ferrite, pearlite, ... Per saperne di più
Isotropic compression is a common material test in soil mechanics. The modified Cam-Clay (MCC) model describes the relation between the void ratio and the logarithm of the pressure. In this example, a cylindrical soil sample under isotropic compression is simulated. It is verified that, ... Per saperne di più
Ion-exchange is a powerful method to separate proteins from solutions and is today readily used in biotechnological and pharmaceutical industry. This model simulates an ion-exchange column for protein adsorption. The fluid phase contains four components: two proteins, solvent, and one ... Per saperne di più
This example demonstrates a benchmark test showing that Electric Currents in Layered Shells physics interface can be used to obtain the same results as when the model is solved with the Electric Currents interface based on a solid 3D structure. Per saperne di più
In this model, a full transient analysis of a loudspeaker driver is performed, which allow the modeling of nonlinear effects. It extends the linear frequency domain analysis done in the Loudspeaker Driver tutorial model. The analysis accounts for nonlinear behavior of the soft iron in ... Per saperne di più
