Model of the sound radiation from a circular duct with uniform flow. The convected acoustic problem is described using the linearized potential flow equations, solved in the frequency domain. The acoustic inlet is treated including higher order modes using the Port boundary condition and ... En savoir plus
For transient acoustic problems, there are different sound pressure level metrics that have been defined in the literature and in measurement standards. These metrics are important to know when comparing results from a transient acoustic simulation to measurements from a sound level ... En savoir plus
The design of antireflective coating plays an important role to increase the transmission of the infrared light that propagates through optical structures such as lens and windows. In this model, we showcase how different bulk structures such as Si and CZT that has the bulk ... En savoir plus
This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from SOLIDWORKS® via the LiveLink™ interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz. En savoir plus
This tutorial demonstrates the use of the Heat and Moisture Flow predefined interface for the modeling of heat transfer and moisture transport in a turbulent air flow, with the quantification of evaporation and condensation on surfaces, and the automatic handling of the associated latent ...

These examples demonstrate how to use a job sequence to perform a programmatic sequence of operations, including solving; saving the model to file; and generating and exporting plot groups, results, and images. In the blog post associated with these files, "How to Use Job Sequences to ... En savoir plus
In this model, two fluids are separated by a multilayer solid elastic structure. An acoustic pressure wave impacts the structure resulting in a reflected wave and a transmitted wave with a loss through the structure. This model investigates the transmission loss through the structure. ... En savoir plus
