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 mutual inductance and induced currents between a single turn primary and twenty turn secondary coil in a concentric coplanar arrangement is computed using a frequency domain model. Each turn of the secondary coil is modeled explicitly. The results are compared against analytic ... Per saperne di più
Many complex fluids of interest exhibit a combination of viscous and elastic behavior under strain. Examples of such fluids are polymer solutions and melts, oil, toothpaste, and clay, among many others. The Oldroyd-B fluid presents one of the simplest constitutive models capable of ...

This is a model of the Brüel and Kjær 4134 condenser microphone. The geometry and material parameters are those of the actual microphone. The modeled sensitivity level is compared to measurements performed on an actual microphone and shows good agreement. The membrane deformation, ... Per saperne di più
This example studies the deflection of a cantilever beam undergoing very large deflections. The beam is modeled using both the Solid Mechanics interface and the Beam interface. The results are compared with each other and with a benchmark solution from NAFEMS. In addition, a linear ... Per saperne di più
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 example shows how to compute thermally induced stresses in a turbine stator blade using the Thermal Stress, Solid interface. The conditions within gas turbines are extreme. The pressure can be as high as 40 bar, and the temperature more than 1000 K. Any new component must therefore ... Per saperne di più
This model simulates a GaN based light emitting diode. The emission intensity, spectrum, and quantum efficiency are calculated as a function of the driving current. Direct radiative recombination across the band gap is modeled, as well as non-radiative Auger and trap-assisted ... Per saperne di più
This app can be used as a design tool to develop an optimized battery configuration for a specific application. The application computes the capacity, energy efficiency, heat generation, and capacity losses due to parasitic reactions of a battery for a specific load cycle. Various ... Per saperne di più
This example solves the heat transfer in an isothermal box aimed at transporting refrigerated articles such as medical materials for 24 hours. In this case, the box has to keep the contents cold for a long period of time while respecting storage temperature restrictions between 2°C and 8 ... Per saperne di più
This tutorial model demonstrates the use of dynamic cyclic symmetry with postprocessing on the full geometry. A 3D impeller with eight identical blades can be divided into eight sectors of symmetry. The model computes the fundamental frequencies for the full impeller geometry and ... Per saperne di più
