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.
In this benchmark example, a semi-elliptical crack at the inner surface of a cylinder is studied. The inside of the cylinder and the crack faces are subjected to a pressure load. The J-integral is calculated along the crack front, and the stress intensity factor is then compared with the ... En savoir plus
When analyzing rotors, it is common that bearings are modeled through their effective dynamic coefficients about a static equilibrium position. This model illustrates how to compute such coefficients for a cylindrical journal bearing. The bearing length is kept much smaller than its ... En savoir plus

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 ... En savoir plus
Mass transport limitations within thin crevices can often result in the local electrochemistry to differ significantly between the crevice opening (mouth) and end (tip), and as a result of the differences in local chemistry, corrosion may occur. This example models crevice corrosion of ... En savoir plus
This tutorial is a benchmark model that reproduces the Testing Electromagnetic Analysis Method (TEAM) Problem 32, which evaluates numerical methods for the simulation of anisotropic magnetic hysteresis. A hysteretic three-limbed laminated iron core is subject to a time-varying magnetic ... En savoir plus
An axisymmetric model of a rigid piston in an infinite baffle is used to exemplify the Exterior Field Calculation feature of the Acoustics Module. The radiation results provided by the COMSOL Multiphysics® software are compared to analytical results for the on-axis radiation ... En savoir plus
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 ... En savoir plus
Polymer hydrogels consist of a crosslinked network of long-chained polymers that has imbibed a large number of solvent molecules. Such materials are used in many biomedical applications, such as targeted drug delivery, tissue engineering, and stimuli-sensitive actuators. This benchmark ... En savoir plus
This tutorial shows how to set up a ray release based on the incident electric field at a boundary. First the Electomagnetic Waves, Frequency Domain interface is used to solve for the electric field of a plane wave. Then rays are released with initial intensity and polarization matching ...
