This model presents a solution to the Transient Electromagnetic Analysis Methods (TEAM) workshop problem 28, “An Electrodynamic Levitation Device”- a benchmark problem involving the dynamic coupling of electromagnetics and rigid body dynamics. An electrodynamic levitation force is ... En savoir plus
Shape optimization with respect to fatigue properties is not supported, but fatigue properties are well correlated with the maximum stress. The model demonstrates how optimization with respect to a p-norm of the von Mises stress can be used to improve fatigue properties without ... En savoir plus
A quadrupole mass filter (QMF) is a key component of a modern mass spectrometer. A QMF uses direct current (DC) and alternating current (AC) electric fields to analyze positive or negative ions by mass to charge ratio. A QMF consists of 4 parallel rods spaced equidistantly, the ratio of ... En savoir plus
Many complex fluids of interest exhibit a combination of viscous and elastic behavior under strain. Examples of such fluids are polymer solutions and melts, oil, toothpaste, and clay, among many others. The Oldroyd-B fluid presents one of the simplest constitutive models capable of ...

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
Lamb wave resonators are useful components for many radio-frequency applications. This tutorial shows how you model an aluminum nitride Lamb wave resonator and perform eigenfrequency and frequency-response analyses to characterize the device. En savoir plus
This model demonstrates the polarization properties for a Gaussian beam incident at an interface between two media at the Brewster angle. The model shows how to use the Electromagnetic Waves, Beam Envelopes physics interface with a User defined phase specification. Matched Boundary ... En savoir plus
A transient model of a capacitor is solved in combination with an external electrical circuit. The finite element model of the capacitor is combined with a circuit model of a voltage source and a resistor. A step change in voltage is applied, and the transient current through the ...
