In conformità con la nostra Quality Policy, COMSOL ha pubblicato una libreria con centinaia di esempi di modelli documentati che vengono regolarmente testati rispetto all'ultima versione del software COMSOL Multiphysics®, compresi i problemi di benchmark di ASME e NAFEMS, così come TEAM problems.
I nostri test di verifica e validazione (V&V) forniscono soluzioni sempre accurate che vengono confrontate con i risultati analitici e i dati di riferimento stabiliti. I modelli documentati qui sotto fanno parte delle Application Library integrate nel software COMSOL Multiphysics®. Includono inoltre valori di riferimento e fonti per un'ampia gamma di benchmark, così come istruzioni passo-passo per riprodurre i risultati sul proprio computer. Questi modelli possono essere usati non solo per documentare l'impegno nella garanzia di qualità del software (SQA) e nella verifica del codice numerico (NCV), ma anche come parte di un programma di formazione interno.
Micromirrors are used in certain MEMS devices to control optical elements. This example of a vibrating micromirror surrounded by air uses the Thermoacoustic-Shell Interaction user interface to model the fluid-solid interaction, and it thus includes the correct viscous and thermal damping ...

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 ... Per saperne di più
Cyclones are used in a variety of applications ranging from the mining industry to vacuum cleaners. The flow in a cyclone is characterized by a very strong swirl, which makes it difficult to simulate. In this tutorial example, the v2-f turbulence model is used to simulate the flow in a ...

Reflective mufflers are best suited for the low-frequency range where only plane waves can propagate in the system, while dissipative mufflers with fibers are efficient in the mid- to high-frequency range. Dissipative mufflers based on flow losses, on the other hand, also work at low ... Per saperne di più
Emulsions consist of small liquid droplets immersed in an immiscible liquid and widely occur in the production of food, cosmetics, fine chemicals, and pharmaceutical products. The quality of the product is typically dependent on the size of the droplets. Simulating these processes can ... Per saperne di più
This example demonstrates the wrinkling of a thin rectangular sheet stretched uniaxially. First, a static analysis is performed to determine the region of negative principal stresses without wrinkling. Next, a prestressed buckling analysis is carried out to find out the linearized ...

The acoustic field in a model of an axially symmetric lined aero-engine duct, based on modal sound transmission, is analyzed. The source is generated by a single mode excitation at a boundary. Sources and nonreflecting conditions are applied using port boundary conditions. The model ... Per saperne di più
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 ...
