Newtonian telescopes, first invented in 1668 by Isaac Netwon, are still used today because of their low cost and simple design. Rays of light propagate from sources located at infinity, into the telescope. The rays reflect off a parabolic mirror, onto a flat mirror, and into the focal ... Mehr lesen
Micropumps are key components of microfluidic systems with applications ranging from biological fluid handling to microelectronic cooling. This model simulates the mechanism of a valveless micropump, that is designed to be effective at low Reynolds numbers, overcoming hydrodynamic ... Mehr lesen
Sensitivity analysis is an efficient way of computing the gradient of an objective function with respect to many control variables. This example uses the pitch and yaw in the top of a truss tower as objective functions. It shows how to compute the sensitivity of these angles with respect ... Mehr lesen
Buckling is a common failure mode for slender structural components. This model shows how the buckling load of a diagonal brace can be maximized, while constraining the volume of the brace. Mehr lesen
When anodizing aluminum, the surface is electrochemically altered to form an abrasive and corrosion-resistive Al2O3 film. The electrode kinetics during the process are only marginally affected as the oxide layer grows, so a stationary analysis of the current distribution is sufficient to ... Mehr lesen

Das Modell basiert auf einer 3D-Darstellung des bestehenden achsensymmetrischen 2D-Modells loudspeaker_driver aus der Application Library der Software. Der Aufbau ... Mehr lesen
This example resembles the well-known double-slit interference experiment often demonstrated in schools with water waves or sound. The model mimics the plane-wave excitation with two thin waveguides leading to slits in a screen and computes the diffraction pattern on the opposite side of ... Mehr lesen
This example demonstrates the usage of current terminal to compute the resistive heating of a busbar. Mehr lesen
Surface plasmon-based circuits are being used in applications such as plasmonic chips, light generation, and nanolithography. The Plasmonic Wire Grating Analyzer application computes the coefficients of refraction, specular reflection, and first-order diffraction as functions of the ... Mehr lesen
Uncertainty Quantification is used to study the effect of manufacturing variation on the performance of 2D Solidly Mounted Resonator (2D SMR). This tutorial shows how resonant frequency is effected by thickness variations of the piezoelectric layer and the Bragg reflector layers. The ... Mehr lesen
