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 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 ...

When modeling the propagation of charged particle beams at high currents and relativistic speeds, the space charge and beam current create significant electric and magnetic forces that tend to expand and focus the beam, respectively. The Charged Particle Tracing interface uses an ... En savoir plus
In this set of verification models and associated documentation, the accuracy of electromagnetic force calculations is investigated. Using various techniques, the total force and torque on a rigid body is determined and compared to analytical models. Using fillets, advanced meshing and ... En savoir plus
Ultrahigh Molecular Weight (UHMW) Polyethylene is a material commonly employed in knee and hip joint replacements. The “small punch test” is designed to assess mechanical properties using very small samples, such that because of their size they can directly be explanted. This example ... En savoir plus
This model simulates the flow around an inclined NACA 0012 airfoil at different angles of attack using the SST turbulence model. The results show good agreement with the experimental lift data of Ladson and the pressure data of Gregory and O’Reilly. 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
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
In this example, the External Stress feature in the Solid Mechanics interface is used to provide the material model with the nonsymmetric stress required in the design of an elastic invisibility cloak. The cloak is a domain with special material properties aimed at shielding a region of ... En savoir plus
In this benchmark model, solid particles are released in a fully developed turbulent channel flow. The particles are subjected to a drag force that includes contributions from the fluid turbulence, implemented using a Continuous Random Walk (CRW) model. Because the turbulence in the ...
