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 model demonstrates how the Free Shape Boundary feature can be used to perform shape optimization on a design found with topology optimization. The model uses the same objective and constraint as the original, which results in a slightly higher stiffness for the same mass. Per saperne di più
Induction pumps are used in high temperature cooling systems. The principle of operation is equivalent to a linear three phase induction motor. The lack of moving parts and the pumped liquid being kept in a hermetically closed system are clear advantages. This model shows how to simulate ... Per saperne di più
Ultrahigh Molecular Weight (UHMW) Polyethylene is a material commonly employed in knee and hip joint replacements. The “small punch test” is designed to assess mechanical properties using very small samples, such that because of their size they can directly be explanted. This example ... Per saperne di più
In this example, two model for brittle damage are used to evaluate the fracture of a notched concrete beam subjected to three point bending. The results are compared with experimental data. Per saperne di più
Lamb-wave resonators are useful components for many radio-frequency applications. This example shows how you model an aluminum nitride Lamb wave resonator and perform eigenfrequency and frequency-response analyses to characterize the device. The tutorial uses the Electric Currents in ... Per saperne di più
This is a benchmark model to test the numerical algorithms in the area of multibody dynamics. This model simulates the dynamic behavior of the slider crank mechanism. This mechanism goes through singular positions during its operation. The acceleration at a point is compared with the ... Per saperne di più
In this example, triaxial and oedometer tests are simulated using the Hardening Soil material model. Both tests exhibit a hyperbolic stress–strain relationship. For the triaxial test, it is confirmed that the axial stress approaches the analytical failure stress asymptotically. In the ... Per saperne di più
A thin-walled metal frame with a central cutout, modeled using the Shell interface, is subjected to twisting and bending. Around the cutout the stresses are higher than the yield stress, thus the material undergoes plastic deformation over the loading history. Per saperne di più
Modern integrated circuits are available as plastic encapsulated microcircuits (PEM). These devices are molded out of polymeric materials and epoxy resins in order to protect the internal semiconductors. Unfortunately, polymeric mold compounds absorb moisture when exposed to a humid ... Per saperne di più
This tutorial explores how pulse reverse plating can be used as an additive-free alternative to attenuate small protrusions during copper metal deposition. By matching the process parameters, including the length of the forward and reverse pulses (duty cycles), a bright mirror-like metal ... Per saperne di più
