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.
Modeling the electrical activity in cardiac tissue is an important step in understanding the patterns of contractions and dilations in the heart. The heart produces rhythmic electrical pulses, which trigger the mechanical contractions of the muscle. A number of heart conditions involve ... Per saperne di più
Inductive devices experience capacitative coupling between conductors at high frequencies. Modeling this phenomenon requires that you describe electric fields that have components both parallel with and perpendicular to the wire. This consideration might lead to the conclusion that a 3D ... Per saperne di più
This model example simulates an air-cooled cylindrical 18650 lithium-ion battery during a charge-discharge cycle, followed by a relaxing period. A lumped (0D) cell model is used to model the battery cell chemistry, and a two-dimensional axi-symmetrical model is used to model the ... Per saperne di più
This app demonstrates the following: Dynamic help system using card stacks Multiple components (1D and 3D) in a single app Toggle buttons in the ribbon for showing different input, hiding/showing geometry selections, and for dynamic help Geometry parts and parameterized geometries ...

Communication masts usually have a framework with a bolted triangular lattice design. The diagonals of the framework are assembled from several parts and welded together. When operating under a given wind load at a specific location, the antenna’s total rotation angle should stay below ... Per saperne di più
This model demonstrates the path of relativistic protons within Earth's magnetic field. Due to the dipole nature of Earth's magnetic field, charged particles, such as electrons and protons, can get trapped in stable configurations within it for long periods of time. These ... Per saperne di più
The following model examines unsteady, incompressible flow past a long cylinder placed in a channel at right angle to the oncoming fluid. The cylinder is offset somewhat from the center of the flow to make the steady-state symmetrical flow unstable. The simulation time necessary for a ... 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
This tutorial uses the submodeling technique to accurately resolve the stress concentrations in a wheel rim. First a global model is solved to obtain the displacements, which are then used as boundary conditions in a local model of the region where the stress concentrations occur. Per saperne di più
Follow this tutorial series to learn about how to work with imported surface meshes. The instructions detail how to import STL files of three vertebrae and two intervertebral discs as well as how to repair holes, misaligned mesh vertices, and intersecting elements. It further ... Per saperne di più
