This model demonstrates the analysis of lightning surges on high voltage transmission line towers. Lightning carrying a current of 10 kA struck one of the tower's shielded wires. The induced voltage at the three-phase conductors are computed. Some highlights of this model: Perform ... En savoir plus
This example models an oil reservoir with two horizontal wells. The reservoir contains two phases, water and oil. Oil is recovered by injecting water through the bottom well, so the oil production rate and the water-oil production ratio over time are computed. En savoir plus
This tutorial models an ICP reactor by solving plasma fluid type equations fully coupled with the homogeneous and time-independent electron Boltzmann equation in the classical two-term approximation. The approximated Boltzmann equation is solved for each position of space and is coupled ... En savoir plus
This tutorial model is of a micro perforated plate (also known as MPP) backed by a vibrating structure. This is a typical configuration in, for example, a MEMS microphone. The vibrating structure is not modeled explicitly, but just assigned a vibration velocity. The vibrating structure ... En savoir plus
Predicting the noise radiation from a dynamic system gives designers insight into the behavior of moving mechanisms early in the design process. For example, consider a gearbox in which the change in the gear mesh stiffness causes vibrations. These vibrations are transmitted to the ... En savoir plus
This tutorial shows the analysis of a car cabin in order to study the performance of a sound system in the low to mid frequency range. The model studies the transient response to an emitted Gaussian modulated harmonic signal solved with the Pressure Acoustics, Time Explicit physics ... En savoir plus
This model computes the transmission probability through an RF coupler using both the angular coefficient method available in the Free Molecular Flow interface and a Monte Carlo method using the Mathematical Particle Tracing interface. The computed transmission probability determined by ... En savoir plus
The topology optimized Tesla microvalve is used as inspiration for a parametrized geometry. The optimization of this geometry takes erosion and dilation of the geometry into account by optimizing over a parametric sweep. In this example the optimization is driven by the worst of the 3 ...

Continuous mixing is used in process equipment to mix components in a single pass. Compared to batch mixing, this operation has the advantage that the tank filling and emptying steps are eliminated, implying that the process can be run without interruptions. A disadvantage of continuous ... En savoir plus
Electrochemical codeposition is a common low-cost method for producing metal alloys. This tutorial model demonstrates electrodeposition of a nickel (Ni)–phosphorous (P) alloy. The model accounts for charge and mass transport of a multitude of species along with multiple electrode ... En savoir plus
