The purpose of this application is to generate response spectra from a time history which can consist of either measured data on a file, or an analytical function. Primarily, the target is to provide input to a response spectrum analysis. The graphs can, however, also be used to ... En savoir plus
This example illustrates the modeling of a tensegrity table. The table is made of two rigid bodies connected through a central wire and four outer wires. Two cases are analyzed. In the first case, the top of the table is loaded with vertically downward acting load of varying magnitude. ... En savoir plus
These models introduce how to perform convolution via the convolution integral, discrete convolution, and convolution theorem. Specifically, they show how to implement convolution by applying these methods to the low-pass filtering of a room impulse response (IR) and the auralization of ... En savoir plus
This verification model analyzes the acoustics of two coupled rooms using the Acoustic Diffusion Equation interface of the Acoustics Module. The results of the model agree with numerical results that are validated against measurements in a reference paper. En savoir plus
In this tutorial the geometry of an occluded ear-canal simulator is optimized to match the acoustic response of a given ear. The target data in this model stems from a simulation of an ear canal, but it can also be based on measurements, or a response specified by a standard. En savoir plus
In this multibody dynamics model of a simple counterweight trebuchet, a parametric sweep is used to study throwing distance as function of the sling length. For more details on performing a multibody analysis of a counterweight trebuchet, see this blog post: What Is the Physics Behind a ... En savoir plus
When a droplet is placed on a substrate on which surface acoustic waves (SAWs) are traveling, the energy of the SAWs is transferred into the droplet to form an acoustic field. The transferred energy is attenuated and generates a streaming flow. This type of streaming enables contactless ... En savoir plus
The Dzhanibekov effect, also called the intermediate axis theorem or tennis racket theorem, describes the behavior of a rigid body with three distinct principal moments of inertia. This simulation app can be used to test the Dzhanibekov effect in three different geometries, including a ... En savoir plus
Gradient-based optimization is an efficient way of computing better values for many control variables. This example optimizes diameters of individual members in a truss structure such that the structure becomes stiffer without adding mass to the structure. The structure will be only be ...

Topology optimization is associated with extreme design freedom which can yield extreme performance. The designs can be easier to manufacture by using milling constraints, at some cost to the performance. This example considers the case of a torsion sphere which is known to feature a ...
