This app demonstrates the following: Using the knob form object Updating the geometry by rotating a knob Provides info if the results are above or below certain critical values Many trucks are equipped with cranes for handling loads and such cranes have a number of hydraulic ... En savoir plus
Inverted elements can prevent large deformations for shape optimization. This model demonstrates how this problem can be circumvented using export/import of the geometry and a model method. The technique is demonstrated on a benchmark problem from topology optimization, where the ... En savoir plus
Creating irregular geometries can be a good solution, even the only option, for some types of applications. These files present a way to use a text file with material properties defined in coordinates to assign different materials even though there is only one regular domain. The same ... En savoir plus
Bearing clearances should be kept minimum to avoid non-synchronous vibration of a rotor. However, a tight clearance reduces the durability of the bearing. This example illustrates modeling of the vibration induced by nonlinear contact for different radial clearances. It is shown that ... En savoir plus
This tutorial demonstrates how to use the temperature and relative humidity computed by the simulation of heat and moisture transport in an insulated roof as inputs for a mold prediction model. The VTT model for mold growth and decline prediction computes a mold index M by solving an ... 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
This example simulates the propagation of a positive streamer in transformer oil under a lightning impulse voltage. The space charge density and the electric field are obtained. The simulated streamer radius agrees well with the measured values. En savoir plus
The purpose of this model is to introduce the specular reflection in Surface-to-Surface Radiation using the ray-shooting algorithm. Different parameters are available to the user to yield better accuracy in the results when using the ray-shooting algorithm. The model is a standard ... En savoir plus
These models introduce how to perform convolution via the convolution integral, discrete convolution, and convolution theorem. Specifically, they show how to implement convolution by applying these methods to the low-pass filtering of a room impulse response (IR) and the auralization of ... En savoir plus
