This is a model of a simple Sagnac interferometer consisting of two mirrors and a beam splitter arranged in a triangle. The entire modeling domain rotates; as a result, the rays propagating in opposite directions in the triangle have different optical path lengths due to the Sagnac ... Mehr lesen
Simulation of Maxwell’s equations in the time domain is useful if the objective of the analysis is to observe a transient phenomenon, to find the time it takes a signal to propagate, or if the materials being modeled are non-linear with respect to the electric or magnetic field strength. ...

Substrate Integrated Waveguides (SIW) can be used in antenna applications. Leaky waves from a slot array on the top surface of the SIW in this model generate a beam in a certain direction that can be steered by choosing a different operating frequency. Mehr lesen
This example models flow in a microchannel heat exchanger by coupling a Laminar Flow interface in 3D to a Pipe Flow interface. By the use of the Pipe Flow interface to model the flow in the microchannels the problem size is significantly reduced. This model showcases the Pipe Connection ... Mehr lesen
This model presents a time-dependent study of a microchannel that is used to infuse and flush another piece of equipment with a fluid. The pressure at the five inlets varies sinusoidally as functions of time, and the velocity vector at the outlet is studied. The model uses an ... Mehr lesen
For an electrochemical reaction to occur, the reacting species usually needs to adsorb to the electrode surface before undergoing reduction or oxidation, after which the resulting product species desorbs back into the electrolyte. If the rate of adsorption or desorption is slow in ... Mehr lesen
In the chemical and biochemical industries, for instance in fermentation processes, reactors having well-mixed conditions and liquid level control are common. This example shows modeling of a 0D ideal system of tank reactors in series with controlled feed inlet and product outlet ... Mehr lesen
Steel structures immersed in seawater can be protected from corrosion through cathodic protection. This protection can be achieved by an impressed external current or by using sacrificial anodes. The use of sacrificial anodes is often preferred due to its simplicity. This example models ... Mehr lesen
Sound is generated by a point source located in the wall of this test bench car interior. The sound pressure level response at a point of measurement is investigated for a range of frequencies and four different mesh resolutions. The model is first solved with the default direct solvers. ... Mehr lesen
This model simulates the velocity of the ionic wind generated by a wire-to-wire corona discharge. Ionic wind, created by the movement of charged particles in an electric field, can be harnessed for various applications, including cooling electronic components and enhancing heat ... Mehr lesen
