This model is a verification case to attest the behavior of turbulence models and wall functions in the boundary layer of a turbulent flow. The velocity and the temperature are compared to the theoretical curves in a wall-resolved and a wall-modeled approach using the Algebraic y+ ... En savoir plus
The Thermal Actuator Surrogate Model Application demonstrates how the computational speed can be increased with the use of a surrogate model. This app demonstrates the following: Adjusting input parameters via sliders, with near-instantaneous updates to the solution retrieved from the ... En savoir plus
This tutorial example shows how to perform a random vibration analysis of a structure using power spectral density (PSD). The computations are based on the modal reduced order model (ROM). En savoir plus
Applying an electric field across a suspension of immiscible liquids may stimulate droplets of the same phase to coalesce. The method known as electrocoalescence has important applications, for instance, in the separation of oil from water. To model electrocoalescence, you need to solve ... En savoir plus
In this tutorial, an uncertainty quantification analysis is performed on the Microstrip Patch Antenna model from the RF Module Application Library to explore how variations in input parameters, such as material properties or geometric variations, impact the antenna’s performance in terms ...

The strength reduction technique is a tool to find the factor of safety (FOS) in geotechnical problems, particularly in slope stability analyses. To determine the factor of safety of the slope, the strength properties in the Mohr–Coulomb model are gradually reduced until failure occurs. ... En savoir plus
This tutorial demonstrates how to model a gyroscope based on the birdbath resonator gyroscope (BRG) design. The BRG is a type of Coriolis vibratory gyroscope (CVG) invented at the University of Michigan as a navigation-grade gyroscope in the mm-scale. This tutorial shows how the ... En savoir plus
Uncertainty Quantification (UQ) is used to study the effect of manufacturing variation on the performance of Piezoelectric Energy Harvester. This tutorial shows how UQ studies are specified for a frequency domain study that calculates the energy harvester's power output. En savoir plus
A tubular centrifuge is a type of centrifugal separation device that is often used for separation of very fine solid particles from a liquid. It can be run in both a continuous and batch type configurations. The device usually consists of a cylindrical rotating bowl with a large aspect ... En savoir plus
Heating of an object from alternating regions is one example where the modeling technique of activating and deactivating physics on domains can be useful. This model demonstrates how you can apply this technique using LiveLink™ for MATLAB®. En savoir plus
