This example simulates 3D unsteady laminar flow past a cylinder in a channel. The inflow velocity profile is time-varying. The lift and drag coefficients are computed, and results show good agreement with those published in the literature. Mehr lesen
Surface plasmon polariton (SPP) as well as other types of surface electromagnetic waves is of great interest due to unique physical properties and application potentials. The models here demonstrate how to simulate SPP propagation and its frequency-momentum dispersion relation. The ... Mehr lesen
Modeling the electrical activity in cardiac tissue is an important step in understanding the patterns of contractions and dilations in the heart. The heart produces rhythmic electrical pulses, which trigger the mechanical contractions of the muscle. A number of heart conditions involve ... Mehr lesen
The first part of the application computes the modes for a straight step index fiber made of silica glass. In the second part, a step index fiber bend with a 3 mm radius of curvature is analyzed with respect to propagating modes and radiation loss. It is shown how to find the power ... Mehr lesen
This app demonstrates the following: Parameterized geometry containing a geometry sequence with if-statements to produce different types of designs Options to set the mesh size A graphical user interface that includes different windows that can be shown or hidden Light Theme Water ... Mehr lesen
This model shows how to use the Free Shape Boundary feature to increase the stiffness of a wrench without increasing its mass. Mehr lesen
Bei der Entwicklung von Mischern geht es oft nicht nur um die Effektivität, sondern auch um andere Faktoren wie die Kosten und die Komplexität der Herstellung. Die drei Modelle untersuchen einen laminaren statischen Mikromischer mit zwei parallelen Sets von Split-Reshape-Recombine ... Mehr lesen
Inductors are used in many applications for low pass filtering or for impedance matching of predominantly capacitive loads. They are used in a wide frequency range from near static up to several MHz. An inductor usually has a magnetic core to increase the inductance, while keeping its ... Mehr lesen
In this tutorial, the propagation of elastic waves in the ground after a seismic event is simulated using a 2D model. The effect of the ground surface topology on the wave propagation is illustrated when an ideal half space is modified with the presence of a small mountain. The model is ... Mehr lesen
This example models a solid oxide electrolyzer cell wherein water vapor is reduced to form hydrogen gas on the cathode, and oxygen gas is evolved on the anode. The current distribution in the cell is coupled to the cathode mass transfer of hydrogen and water and momentum transport. Two ... Mehr lesen
