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.
In this example, a heat-conduction problem with phase change in a porous material is solved, and the results are compared with the analytical solution, also known as the Lunardini solution. This is the first benchmark case from the InterFrost project, which was initiated to compare ... Per saperne di più
In this example, the micromechanical properties of a piezoelectric fiber composite are studied. The homogenized electromechanical properties of the composite are derived from the individual microscopic properties of matrix and fiber. Per saperne di più
Squeeze film dampers are components that provide additional damping to rotating machines. To simplify the modeling of a rotor assembly, squeeze film dampers are modeled in terms of their damping coefficients which are a functions of the journal location in the damper. This model computes ... Per saperne di più
This benchmark model simulates a GaAs nanowire using the self-consistent Schrödinger-Poisson theory to compute the electron density and the confining potential profiles. The predefined Schrödinger-Poisson multiphysics coupling feature is combined with the dedicated Schrödinger-Poisson ... Per saperne di più
Classical MHD benchmark problem was solved analytically by J. Hartmann. He considered laminar incompressible flow between two planes (in planar duct) in transversal imposed magnetic field under next assumptions: * fully developed flow (far from inlet) * fluid properties are constant * ...

This benchmark example builds two models of a cross-bridge Kelvin resistor used for extracting the specific contact resistivity. The first model simulates the system in 3D, using the contact resistance feature built in the Semiconductor interface. The other model is a 2D approximation of ... Per saperne di più
In this model, two flat end mirrors are placed at a distance and a spherical lens is inserted in the middle of the cavity. A ray is released from a point inside the cavity. Then the ray is traced for a predefined time period that is sufficiently long. Ray tracing continues until the ... Per saperne di più
This model showcases how to solve for the scattered field when knowing the incident field for three different types of scatterer, i.e. an infinitely rigid one, a cavity and an elastic inclusion. This formulation can be useful when the scatterer is in the far-field of the source, such ... Per saperne di più
This setup demonstrates how the characteristics of turbulent flow in a channel are modified by the presence of an adjacent porous region. Asymmetric velocity profiles, higher turbulence levels, and higher friction coefficients both at the solid wall and the fluid-porous interface are ... Per saperne di più
This tutorial model demonstrates how to estimate the material parameters of a combined hardening elastoplastic material model given cyclic shear data. Per saperne di più
