This tutorial model shows how to set up a model of a pulsed capacitive discharge. The on pulse consists of 10 periods of excitation at 13.56MHz, followed by no excitation for 100 periods. The I-V characteristics, the electron density, temperature and plasma potential are studied. En savoir plus
This tutorial model illustrates how to calculate the pressure drop and initial flow rate in a pipe system connected to water tank. The Pipe Flow interface contains ready to use friction models accounting for the surface roughness of pipes as well as pressure losses in bends and valves. En savoir plus
This tutorial shows how to use the Optimization interface to perform electrode kinetics parameter estimations based on polarization data. A zero-dimensional electrode polarization model is defined that separates kinetics expressions for the metal dissolution and the oxygen reduction ... En savoir plus
This type is one of the most popular laser cavities. In particular, it is often used for the Ti-doped sapphire femto-second laser. The stability of the laser cavity is analyzed by releasing a ray inside the cavity and is traced for a predefined time period that is sufficiently long. ... En savoir plus
This example demonstrates how to import and repair a surface mesh from an STL file, and to create a mesh to simulate nasal spray application inside the human upper airways. It further demonstrates how to combine the repaired mesh with the geometry of a nasal spray, then to remesh and ... En savoir plus
This is a benchmark model for the 2D axisymmetric formulation of the Electromagnetic Waves, Frequency Domain interface that is available with the RF Module. The problem is to find the resonant frequencies and fields inside an axisymmetric cavity with rectangular cross-section and ... En savoir plus
This model studies the natural frequencies of a pre-tensioned string using the 2D Wire interface. This is an example of “stress stiffening”; in fact the transverse stiffness of wire elements is directly proportional to the tensile force. Strings made of piano wire have an extremely high ...

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
A centrifugal governor is used to control the speed of rotating machinery. One of the most common applications is in controlling the RPM of an engine by regulating the fuel supply. This model illustrates the functioning of a spring loaded centrifugal governor. The dynamics of the ... En savoir plus
This model shows modeling of a sphere falling on a water surface. Specifically, it models the oscillating motion of a buoyant sphere as it falls through air and interacts with the air-water interface to finally float on water.
