This model simulates the initiation of streamers from suspended metal particles, their propagation under a high electric field, and their subsequent merging. The discharge current flows into the metal particles, which are maintained at equal potential. These suspended particles enhance ... En savoir plus
A 3D model is used to simulate the cooling of a bevel gear from an austenitic state. Phase material properties and phase transformation data are imported into the model. The final phase composition and the residual stress state are computed. Phenomena such as thermal strains, phase ... En savoir plus
This app demonstrates the following: Dynamic help system using card stacks Multiple components (1D and 3D) in a single app Toggle buttons in the ribbon for showing different input, hiding/showing geometry selections, and for dynamic help Geometry parts and parameterized geometries ...

This model simulates the flow through a uniform inclined screen using the Screen feature in Single-Phase Flow physics and compares the results with an analytic solution. En savoir plus
In this benchmark model, solid particles are released in a fully developed turbulent channel flow. The particles are subjected to a drag force that includes contributions from the fluid turbulence, implemented using a Continuous Random Walk (CRW) model. Because the turbulence in the ...

This example provides a walkthrough on how to simulate the basic radiated emission of a printed circuit board and its immunity response from outside noise. First, when one of the microstrip lines is excited, the crosstalk to an adjacent printed line and the radiated field, through an ... En savoir plus
In this tutorial, the acoustic properties of a wax guard are analyzed. A wax guard is a small perforated mesh used to protect the receiver (the miniature loudspeaker in a hearing aid) used for receiver-in-the-ear (RITE) or receiver-in-canal (RIC) hearing aids. Because of the very small ... En savoir plus
This model presents a practical and efficient method to compute the sound transmission loss (STL) through a building component, specifically this example treats the case of a concrete wall. The method used here is valid as long as the component has little influence on the acoustic field ... En savoir plus
Manual design optimization typically requires numerous sweeps over a parameterized geometry, but it does not guarantee optimal performance under given conditions. Shape optimization removes the need for explicit parameterization and can achieve comparable or even better performance in a ... En savoir plus
This example describes the cooling and solidification, from melt to solid metal, in a continuous casting process. The model includes nonisothermal properties, temperature distribution, flow field, and phase change. This example uses the arbritrary Lagrangian-Eulerian method for modeling ... En savoir plus
