In conformità con la nostra Quality Policy, COMSOL ha pubblicato una libreria con centinaia di esempi di modelli documentati che vengono regolarmente testati rispetto all'ultima versione del software COMSOL Multiphysics®, compresi i problemi di benchmark di ASME e NAFEMS, così come TEAM problems.
I nostri test di verifica e validazione (V&V) forniscono soluzioni sempre accurate che vengono confrontate con i risultati analitici e i dati di riferimento stabiliti. I modelli documentati qui sotto fanno parte delle Application Library integrate nel software COMSOL Multiphysics®. Includono inoltre valori di riferimento e fonti per un'ampia gamma di benchmark, così come istruzioni passo-passo per riprodurre i risultati sul proprio computer. Questi modelli possono essere usati non solo per documentare l'impegno nella garanzia di qualità del software (SQA) e nella verifica del codice numerico (NCV), ma anche come parte di un programma di formazione interno.
This example describes how to simulate the self-lubricating phenomenon of a liquid lubricant in a journal bearing. A porous bushing is press-fitted to a bearing and saturated with a lubricant. It acts as a reservoir for the redistribution of the thin film of lubricant between regions of ... Per saperne di più
The model is defined as a benchmark case in norm 15026:2007 annex A. The purpose of the model is to calculate the temperature and moisture profiles at different times after a change in the external conditions (temperature and relative humidity) inside a wall material (kind of concrete). ...

In this model a Knowles ED23146 receiver (miniature loudspeaker) is connected to a test set-up consisting of a 50 mm (1 mm diameter) earmold tube and a so-called 0.4-cc coupler. The receiver is modeled using a lumped spice network and connected to the finite element domain at the tube ... Per saperne di più
Electrochemical supercapacitors feature relatively higher energy densities than conventional capacitors. With several advantages, such as fast charging, long charge–discharge cycles, and broad operating temperature ranges, electrochemical supercapacitors have found wide applications in ...

This example demonstrates the wrinkling phenomenon in a thin sheet stretched uniaxially. The modified membrane theory, which incorporates the wrinkling model, ensures noncompressive principal stresses in the wrinkled region. The analytical results are compared to the numerical results.

In this example, the Extended Barcelona Basic Model (BBMx) is used to model oedometer, uniaxial swelling, triaxial, and constrained swelling tests on bentonite clays in order to recover the hydromechanical characteristics of the soil samples. There is a good qualitative agreement ... Per saperne di più
At the electrode-electrolyte interface, there is a thin layer of space charge in a diffuse double layer. This may be of interest when modeling devices such as electrochemical capacitors and nanoelectrodes. This tutorial example shows how to couple the Nernst-Planck equations to the ...

In this tutorial model, the far-field radiation pattern of a dipole antenna is computed in a 2D axisymmetric model component. Then, in a separate 3D model component, a ray is released using the far-field radiation pattern to initialize the ray's intensity, polarization, and phase. Per saperne di più
This tutorial model demonstrates how to set up a parameter estimation study for fitting the material parameters of an Ogden hyperelastic model to experimental data. The procedure considers multiple load cases under large deformations, which is often necessary to obtain constitutive ... Per saperne di più
