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 tutorial example of a comb drive tuning fork gyroscope is kindly provided by Dr. James Ransley at Veryst Engineering, LLC. The model demonstrates fully parameterized geometry, extensive use of selection features, implementation of analytic formulas for the electromechanical forces ... Per saperne di più
A waveguide filter is designed using shape optimization by moving and scaling rectangles in the geometry. The irises of the initial geometry are optimized to ensure good bandpass response and out-of-band rejection, while maintaining the double mirror symmetry. Per saperne di più

Wave heated discharges may be very simple, where a plane wave is guided into a reactor using a waveguide, or very complicated as in the case with ECR (electron cyclotron resonance) reactors. In this example, a wave is launched into reactor and an Argon plasma is created. The wave is ... Per saperne di più
This model of a circular waveguide demonstrates how to use ports with numerical solution of the port modes. It illustrates how to align the polarization of degenerate port modes and in particular how to model and excite the TE11 mode of circular waveguides in 3D. Per saperne di più
A spiral slot antenna provides a conformal design and can be used for communication, sensing, tracking, positioning, and many applications in different microwave frequency bands due to its wide-band frequency response. This model shows how to build a spiral geometry using parametric ... Per saperne di più
An iron sphere in a magnetic field is an excellent textbook example to demonstrate the effects of a magnetic field interacting with a permeable material. This tutorial series is designed as an introduction to numerically modeling electromagnetic effects with COMSOL. This series ... Per saperne di più
This model shows how to compute the S-parameter for a piezoelectric MEMS device by extending the tutorial Thin-Film BAW Composite Resonator. The measurement of S-parameter is commonly used to characterize such devices for RF applications. The terminal feature in the Electrostatics ... Per saperne di più
Biconical antennas are popular for very high frequency (VHF) measurement because they support a wide frequency range. They are also useful for electromagnetic compatibility (EMC) testing where the antenna can be used as an RF source in susceptibility or immunity test. This model ... Per saperne di più
Feeding a waveguide from a coaxial cable is a straightforward way to achieve electromagnetic waves inside a waveguide. Due to its small size and circular shape, the cable contributes significantly to the overall size of the problem. It is therefore necessary to keep the cable as short as ... Per saperne di più
