This model is a verification case to attest the behavior of turbulence models and wall functions in the boundary layer of a turbulent flow. The velocity and the temperature are compared to the theoretical curves in a wall-resolved and a wall-modeled approach using the Algebraic y+ ... En savoir plus
UHF RFID tags are widely used for identifying and tracking animals. This model simulates a passive radio-frequency identification (RFID) tag for the UHF frequency range. With respect to the chip transponder’s complex impedance, a reflection coefficient is computed. This is done using an ... En savoir plus
Voltammetry is modeled at a microelectrode of 10um radius. In this common analytical electrochemistry technique, the potential at a working electrode is swept up and down and the current is recorded. The current-voltage waveform ("voltammogram") gives information about the reactivity and ... En savoir plus
This model demonstrates how to simulate surface plasmon polaritons in a thin metal layer embedded in dielectric layers. It calculates the dispersion and propagation length of surface plasmon polaritons as a function of photon energy. En savoir plus
The drift velocity of Ar+ is calculated using a Monte Carlo simulation in which the elastic collisions of Argon ions with ambient neutrals are explicitly modeled. The model uses energy-dependent collision cross-section data from experiment. The average ion velocity values are consistent ... En savoir plus
This tutorial uses the submodeling technique to accurately resolve the stress concentrations in a wheel rim. First a global model is solved to obtain the displacements, which are then used as boundary conditions in a local model of the region where the stress concentrations occur. En savoir plus
As oil flows through a pipeline section heat is released due to the work of internal friction forces in the fluid. With good insulation of the pipeline, this generated heat can be used to avoid preheating of the oil, despite the fact that it is to be transported in a cold environment ... En savoir plus
Example for a geometry sequence to create a ship hull using Loft. The different cross sections are defined using Dimensions and Constraints. En savoir plus
This model demonstrates how to use the Polynomial Shell feature to increase the lowest Eigenfrequency of a shell by deforming its shape. En savoir plus
In this example, the Bergstrom–Boyce material model is used to capture the nonequilibrium behavior of carbon-black-filled chloroprene rubber under a strain history that alternates compression with relaxation. Results are verified against experimental and numerical results taken from ... En savoir plus
