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.
In this benchmark model for blood flow in a centrifugal pump, simulations are performed for several flow rates and pump speeds. The modeled geometry is taken from the FDA’s Computational Round Robin and the results are in good agreement with the experimental data. The computed shear ... Per saperne di più
A tonpilz transducer is used for relatively low frequency, high power sound emission. It is one of the popular transducer configurations for SONAR applications. The transducer consists of piezoceramic rings stacked between a head mass and a tail mass which are connected by a central ... Per saperne di più
This example simulates 3D unsteady laminar flow past a cylinder in a channel. The inflow velocity profile is time-varying. The lift and drag coefficients are computed, and results show good agreement with those published in the literature. Per saperne di più
This model couples the Navier Stokes equations and the heat transfer equations to examine density driven flow of free fluids. Here the fluid is in a square cavity with a heated wall. The buoyancy force is a Boussinesq term added to the Navier-Stokes equations. The equation is ... Per saperne di più
The Ahmed body represents a simplified, ground vehicle geometry of a bluff body type. Its shape is simple enough to allow for accurate flow simulation but retains some important practical features relevant to automobile bodies. This model describes how to calculate the turbulent flow ... Per saperne di più
This benchmark models two-phase flow in a porous medium in 1D, where the flow can be analytically described by the Buckley-Leverett equation. Per saperne di più
This is the model of an occluded ear canal simulator (a generic 711 coupler). Besides certain details the geometry corresponds to the Brüel & Kjær Ear Simulator Type 4157. The real life couplers are used for simulating the acoustics of a standardized human ear canal and can be used ... Per saperne di più
This example is a benchmark problem for simulating phase change in porous media. It studies the melting process of an ice inclusion within porous media and therefore demonstrates how to couple Darcy's Law with the Heat Transfer in Porous Media interface including phase change. Per saperne di più
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 ... Per saperne di più
