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.
This example models an oil reservoir with two horizontal wells. The reservoir contains two phases, water and oil. Oil is recovered by injecting water through the bottom well, so the oil production rate and the water-oil production ratio over time are computed. En savoir plus
The standard biventricular cardiac model is used to show how to set up fiber directions in a complex geometry. The fibers are then used to model the large deformation of the myocardium with the Holzapfel-Gasser-Ogden anisotropic material model. The Aliev-Panfilov equations are included ... En savoir plus
This model simulates a simple three-dimensional axisymmetric Helmholtz resonator, a classic acoustics model of a resonating circuit with a known theoretical solution. The idealized version considered here consists of a tube and a closed volume in series which are exposed to a pulsatile ... En savoir plus
In this example, the homogenized elastic and viscoelastic properties of a particulate composite are computed based on the individual properties of elastic particles embedded in a viscoelastic matrix. Periodic boundary conditions are applied to a unit cell of the particulate composite ... En savoir plus
Many piezoelectric materials are ferroelectric. Ferroelectric materials exhibit nonlinear polarization behavior, such as hysteresis and saturation at large applied electric fields. In addition, the polarization and mechanical deformations in such materials can be strongly coupled due to ... En savoir plus
This model shows how to implement an anisotropic, incompressible, hyperelastic material for modeling soft collagenous tissue in arterial walls. The hyperelastic material model implemented is based on the articles: Holzapfel, G. A., Gasser, T. C., & Ogden, R. W. (2000), A new ... En savoir plus
This is a benchmark model for an axisymmetric transient thermal analysis. The temperature on the boundaries changes from 0 degrees C to 1000 degrees C at the start of the simulation. The temperature at 190 s from the anlysis is compared with a NAFEMS benchmark solution. En savoir plus
This model solves the Testing Electromagnetic Analysis Methods (TEAM) problem 7, “Asymmetrical Conductor with a Hole”—a benchmark problem concerning the calculation of eddy currents and magnetic fields produced when an aluminum conductor is placed asymmetrically above a multi-turn coil ...

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 ... En savoir plus
This model is a benchmark for three-phase flow commonly used in food processing, pharmaceutical industry, and chemical processing. The results are validated against data reported in the literature. A gas bubble rises through two layers of liquid, a lighter liquid resting on top of a ... En savoir plus
