This model demonstrates a technique for partitioning a mesh based upon the element type. By first meshing with a boundary layer and then partitioning and creating a new mesh, it is possible to avoid modeling the interior volume of inductively heated parts, where the skin depth is small ...

This model demonstrates the filtration of grains of three different sizes as they pass through two vibrating sieves of different hole sizes. En savoir plus
When computing ray intensity in 2D axisymmetric models, the wavefront associated with the propagating ray is treated as a spherical or ellipsoidal wave, instead of a cylindrical wave. This tutorial example illustrates how to set up several important features using the Ray Acoustics ... En savoir plus
In this model, the transmitter (microstrip patch) and receiver (Yagi–Uda) antennas are modeled simultaneously in the FEM domain and are coupled with FEM–BEM coupling. The results are compared with the analytical Friis transmission formula. In detail, the emw and emw2 interfaces find out ... En savoir plus
In food industries, microwave heating is gaining attention over a conventional heating treatment because of several advantages such as precise process control, speed of heating, fast turn-on and turn-off time, etc. In this model, a high directional Yagi-Uda antenna is used to heat up ...

This model shows how to simulate moisture redistribution inside a wall with capillary active interior insulation. The wall consists of three layers: brick, mortar and insulating material. At the beginning of simulation, there is a sudden change in vapor pressure and temperature at ... En savoir plus
In this verification example, the built-in functionality for calculating dynamic coefficients in hydrodynamic bearings is validated. The results are compared with those obtained using the finite perturbation method to ensure consistency and accuracy. The model showcases how numerical ... En savoir plus
This model is used on "Heat Transfer with Radiation in Participating Media and the Discrete Ordinates Method" to compare quadrature sets used in the method of discrete ordinates. The reference analytical solution of incident irradiation is obtained with 256 discrete directions. Errors in ... En savoir plus
Electrode balancing is an important factor in the design of lithium-ion batteries. In this model, use the experimental open-circuit voltage of a cell and some basic assumptions, followed by an optimization solver, to find a proper electrode balancing. Get more details in this ... En savoir plus
Bicycle wheels are laced tangentially if they are intended to be used with disc brakes, because a radial pattern gives rise to larger forces in the rim. Otherwise, these rim forces are largely independent of the braking force. En savoir plus
