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 models how the relative humidity of the inlet gases impacts the performance of a low-temperature polymer electrolyte membrane-electrode assembly. The model includes humidity-dependent ionomer (electrolyte) conductivities, gas phase mass transport and water ionomer ... Per saperne di più
Battery electrodes featuring large heterogeneities in terms of particle sizes may sometimes not be adequately described by homogenized models using one single particle size only. As an alternative to adding multiple instances of the Additional Porous Electrode material node, this ... Per saperne di più
This verification model uses the Electromagnetic Waves, Boundary Elements interface to simulate the RCS of perfectly conducting sphere. The simulated result is compared to analytical calculation to verify the accuracy. Per saperne di più
This example demonstrates how you can use modeling to investigate the performance of different hydrodynamic journal bearings. The model uses the Hydrodynamic Bearing interface, which solves the Reynolds equation to compute the pressure developed in a thin fluid film for four different ... Per saperne di più
This tutorial model solves the Gross–Pitaevskii Equation for the vortex lattice formation in a rotating Bose–Einstein condensate bound by a harmonic trap. The equation is essentially a nonlinear single-particle Schrödinger Equation, with the inter-particle interaction represented by a ... Per saperne di più
The elastic cantilever beam is one of the elementary structures used in MEMS designs. This model shows the bending of a cantilever beam under an applied electrostatic load. The model solves the deformation of the beam under an applied voltage. Per saperne di più
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. The secondary coil is modeled using a homogenized approach which does not explicitly consider each turn ... Per saperne di più
The copper current collector on negative graphite electrodes in lithium-ion batteries have been seen to dissolve at over discharge. This can be a safety concern as the dissolution damages the current collector irreversibly and dissolved copper ions can redeposit and form dendrites. ... Per saperne di più
In these tutorial series, we demonstrate how to use the Offset Faces and Transform Faces operations as a way to reparameterize existing holes in a bracket geometry imported from a STEP file. The mass of the bracket is minimized with limits for both the lowest natural frequency, and for ... Per saperne di più
Removing halogen groups from hydrocarbons is an important reaction step in several chemical processes. One application is water purification. Other examples involve organic synthesis, where the removal of halogen groups serves as a starting point for carbon-carbon coupling reactions. ... Per saperne di più
