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 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
Powder compaction is a key process in powder metallurgy, where it gives the flexibility to produce quality products of complex shapes for sintering. The density of the compact is a key factor to determine the overall quality of the sintered product, as regions with lower density could ... En savoir plus
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. En savoir plus
A simple equivalent circuit model approach is presented for Nickel metal hydride batteries. The 0D model consists of resistor, capacitor, current source and state-of-charge based voltage source (SOC). An Arrhenius type dependence is used to account for self-discharge. All model ... En savoir plus
In this model the high speed turbulent gas flow in a converging and diverging nozzle is modeled using the High Mach Number Flow interface. The diffuser is transonic in the sense that the flow at the inlet is subsonic, but due to the contraction and the low outlet pressure, the flow ... 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
This example reproduces a NAFEMS benchmark in which a plate with an angle crack is subjected to tensile loading. The J-integral is calculated and the stress intensity factors for Mode I and Mode II are compared to the benchmark results for several crack angles. En savoir plus
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 ... En savoir plus
The copper current collector on negative graphite electrodes in lithium-ion batteries have been seen to dissolve at over discharge. This can be a safety concern as the dissolution damages the current collector irreversibly and dissolved copper ions can redeposit and form dendrites. ... En savoir plus
In this model, sound created by a vibrating piston radiates through a baffled pipe. The impedance is measured and then used in an impedance boundary condition that replaces the surrounding air domain. This technique can be employed to reduce solution time and memory usage for large ... En savoir plus
