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 acoustic field in a model of an axially symmetric lined aero-engine duct, based on modal sound transmission, is analyzed. The source is generated by a single mode excitation at a boundary. Sources and nonreflecting conditions are applied using port boundary conditions. The model ... Per saperne di più
This model simulates the propagation of a positive streamer in a weak electric field where the process of photoionization is essential to provide seed electrons at the front of the streamer head. The simulated electric field and electron density as a function of time agree well with that ... Per saperne di più
This example exemplifies how to model the switching between current and voltage excitations in Terminal boundary conditions. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Control Current and Voltage Sources with the AC/DC Module". Per saperne di più
In this example, the etching of silicon in a CF4/O2 plasma reactor is studied using a global model. Parametric sweeps for ion energy and oxygen mole fraction are computed. Per saperne di più
This example investigates the electrical and thermal characteristics of a welding argon arc created in a point-to-plane configuration. The discharge is assumed to be in local thermodynamic equilibrium. The electric arc is considered a conductive fluid medium and is modeled using a ... Per saperne di più
Heating of an object from alternating regions is one example where the modeling technique of activating and deactivating physics on domains can be useful. This model demonstrates how you can apply this technique using LiveLink™ for MATLAB®. Per saperne di più
In this model, you build and solve a 2D beam model using the 2D Structural Mechanics Beam interface. This model describes the eigenfrequency analysis of a simple geometry. A point mass and point mass moment of inertia are used in the model. The two first eigenfrequencies are compared ... Per saperne di più
Light Detection And Ranging (LIDAR) is used extensively in self-driving cars to perform the quantitative ranging of the surroundings obstacles. The LIDAR system consists of a laser beam which gets broadened using a MEMS mirror with a particular horizontal and vertical field of view ... Per saperne di più
This model illustrates how to simulate a periodic homogenization process in a space dependent chemical reactor model. This homogenization removes concentration gradients in the reactor at a set time interval. The model demonstrates a technique by which you can first stop the time ... Per saperne di più
This tutorial illustrates the use of the connecting features in the Heat Transfer in Solids and Heat Transfer in Shells interfaces, to couple them to a Lumped Thermal System interface. The results obtained with the solid and shell models are compared. Per saperne di più
