Conformément à notre Politique de qualité, COMSOL maintient une bibliothèque de centaines d'exemples de modèles documentés qui sont régulièrement testés avec la dernière version du logiciel COMSOL Multiphysics®, notamment des benchmarks de référence en provenance de l'ASME et de NAFEMS, ainsi que des problèmes TEAM.
Notre suite de tests de vérification et de validation (V&V) fournit des solutions précises qui sont comparées aux résultats analytiques et aux données de référence établies. Les modèles documentés ci-dessous font partie des bibliothèques d'applications intégrées du logiciel COMSOL Multiphysics®. Ils comprennent des valeurs de référence et des sources documentaires pour un large éventail de benchmarks, ainsi que des instructions étape par étape pour reproduire les résultats attendus dans votre propre environnement de travail. Vous pouvez utiliser ces modèles non seulement pour documenter vos efforts en matière d'assurance qualité logicielle (SQA) et de vérification de code numérique (NVC), mais aussi dans le cadre d'un programme de formation interne.
Laminated shells made of carbon fiber reinforced polymer (CRFP) are common in a large variety of applications due to their high strength-to-weight ratio. The widespread attention to laminated shells is due to their diverse applications in aerospace, marine, automotive, and various ... En savoir plus
Zinc-Silver oxide (Zn-AgO) batteries are used in different industries due to their high capacity per unit weight. In this work, discharge of a Zn-AgO battery is simulated using the Battery with Binary Electrolyte interface. The electrochemical reactions in the positive and negative ... En savoir plus
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 ... En savoir plus
An important and interesting phenomenon with supersonic flows are expansion fans, which take place when the flow encounters a convex or expansion corner. The direction of the flow changes smoothly across the fan, while the Mach number increases. This 2D example models an expansion fan ... En savoir plus
As reactant monomer converts into polymer chains, the density of the reacting mixture often changes notably. In this example you will look at how this effect impacts the total production of polymer in a process. The liquid phase polymerization takes place in a semibatch reactor, where ... En savoir plus
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 ... En savoir plus
This model exemplifies the basic principles of crevice corrosion and how a time-dependent study can be used to simulate the electrode deformation. The model is in 2D and the polarization data for the corrosion reaction is taken from a paper by Absulsalam and others. The model and the ... En savoir plus
Experiments on dry and wet soil samples are performed to understand their behavior under different loading conditions. In this example, the Extended Barcelona Basic (BBMx) soil model is used to simulate the wetting and drying paths in partially saturated soil samples under cyclic ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
