Geometric Parameter Optimization of a Tuning Fork

This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Solid Edge via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz.

Acoustic-Solid Interaction with two Perfectly Matched Layers (PMLs) - new

This small tutorial model shows how to set up a model with both a solid mechanics and a pressure acoustics domain including two perfectly matched layers (PMLs), one for each physics.

Inflation of a Spherical Rubber Balloon - Membrane Version

The purpose of this model is to illustrate how the Membrane interface can be used to model thin hyperelastic structures. The example is identical to the Model Library model 'Inflation of a spherical rubber balloon', except that the Membrane interface is used instead of the Solid Mechanics interface.

Notch Approximation to Low-Cycle Fatigue Analysis of Cylinder with a Hole

A load carrying component of a structure is subjected to multi-axial cyclic loading during which localized yielding of the material occurs. In this model you perform a low cycle fatigue analysis of the part based on the Smith-Watson-Topper (SWT) model. Due to localized yielding, you can use two methods to obtain the stress and strain distributions for the fatigue evaluation. The first method ...

Accelerated Life Testing

Fatigue testing of nonlinear materials with creep mechanism is a time consuming process. In accelerated life testing the experiment time is greatly reduced by subjecting the material to testing conditions in excess of the operating one. In the model an aggressive thermal load cycle is simulated and its effect on the fatigue life of a solder joint is examined. This example demonstrates how to ...

Outgassing Pipes

This benchmark model computes the pressure in a system of outgassing pipes with a high aspect ratio. The results are compared with a 1D simulation and a Monte-Carlo simulation of the same system from the literature.

Small Concert Hall Analyzer

Designing structures and open spaces with respect to sound quality is important for concert halls, outdoor environments, and even the rooms of a house. Simulating acoustics in the high-frequency limit, where the wavelength is smaller than the geometrical features, can be done with ray acoustics. This application analyzes the acoustics of a small concert hall using the Ray Acoustics physics ...

Caughey-Thomas Mobility

With an increase in the parallel component of the applied field, carriers can gain energies above the ambient thermal energy and be able to transfer energy gained by the field to the lattice by optical phonon emission. The latter effect leads to a saturation of the carriers mobility. The Caughey Thomas mobility model adds high field velocity scattering to an existing mobility model (or to a ...

Corner Cube Retroreflector

A corner cube retroreflector can be used to reflect rays so that their reinitialized trajectories are parallel to their initial trajectories, regardless of the angle of incidence. This tutorial model shows how to simulate the reflection of a bundle of rays at a cube corner retroreflector using the Geometrical Optics interface.

Mixing of Water in a Flat Bottom Mixer - new

This tutorial example simulates the flow in a flat bottom mixer containing, agitated by a pitched four blade impeller, where the fluid is water, and flow is assumed to be turbulent. The flow in the mixer is modeled using the k-ε turbulence model, and a time-dependent simulation corresponding to 30 revolutions of the impeller is performed in order to reach the operating conditions of the ...
