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.
The double barrier structure is of interest because of its application in semiconductor devices such as resonant-tunneling diodes. This verification example demonstrates the Schrödinger Equation interface to set up a simple 1D GaAs/AlGaAs double barrier structure to analyze the ... Per saperne di più
This model demonstrates alternative implementations used for describing a thin layer and the impact of the choice on the continuity of the displacement and stress fields. It is shown how a perfect interface can be obtained by asymptotically changing the material parameters. Per saperne di più
This model serves the purpose of validation and verification of the Linear Elastic Material, Layered model in the Shell interface. In COMSOL Multiphysics, composites are analyzed either based on Layerwise 3D elasticity theory through the Layered Shell interface or based on FSDT-ESL ... Per saperne di più
This simple example covers the heating of a finite slab and how the temperature varies with time. We will set up the problem in COMSOL Multiphysics after which we compare the solution to the analytical solution. Per saperne di più
Unwanted arcing can have serious adverse effects on electrical and electronic equipment and systems. To improve the understanding and prediction of arc dynamics, it is crucial to conduct multiphysics simulations of transient arc processes. This model features a 3D simulation of transient ...

This verification model of nonisothermal turbulent flow over a flat plate compares the heat transfer coefficient obtained from simulation with theoretical values based on Nusselt number correlation functions that can be found in the literature. Per saperne di più
The Bessel panel is a way to arrange a number of loudspeakers so that the angular sound distribution resembles that of a single speaker. This model combines five Bessel panels in the same pattern to approximate a purely radial sound field. The speakers are driven with different ... Per saperne di più
In this example, it is demonstrated how to extend the built-in linear elastic material model to a Cosserat material through the addition of microrotation degrees of freedom. A cylindrical bar under pure torsion is analyzed and the effect of the Cosserat length scale parameter on the ... Per saperne di più
This example shows the behavior of the coupled damage-plasticity material model for concrete when subjected to different loading conditions. Per saperne di più
This tutorial simulates a small vibrating hemispherical particle in water. The particle has a radius of 1 mm and is oscillating in the axial direction at a frequency of 50 kHz. The vibrations induce acoustic waves in the fluid. The example demonstrates how to set up a thermoviscous ... Per saperne di più
