The tonpilz (sound mushroom) piezo transducer is a transducer for relatively low frequency, high power sound emission. The transducer consists of piezoceramic rings stacked between massive ends and pre-stressed by a central bolt. The...
A plane TE-polarized electromagnetic wave is incident on a gold nanoparticle on a dielectric substrate. The absorption and scattering cross sections of the particle are computed for a few different polar and azimuthal angles of...
This is a model of the pressure wave propagation in a muffler for a combustion engine. The approach is general for analysis of damping of propagation of harmonic pressure waves. The model shows how 3D acoustics can be modeled in fairly...
This model simulates a tuning fork for tuning musical instruments which, if correctly designed, should sound the note of A, 440 Hz. It computes the fundamental eigenfrequency and eigenmode for the tuning fork. Although the example seems...
This model shows how a flow model can be coupled to a process control mechanism. Controlling application parameters according to other application parameters is important within process engineering. Most control mechanisms use the...
This is a model from electric impedance tomography, a method of imaging the interior permittivity distribution of a body by measuring current and voltage at the surface. This model demonstrates how the shape and placement of figures...
This is a variant on the heat transfer model library model "RF Cancer Therapy" which includes a damage integral calculation to estimate the extent of cancer necrosis. The damage integral is based on an energy-absorption method rather...
You can now use image data to represent 2D material distributions or to identify regions with different materials by their color or gray scale. Images used in this way can have many origins such as scanning electron microscope (SEM),...
This model approximates 3D spherical transport using a 1D model. Many models of industrial-transport problems allow the assumption that the problem is spherically symmetric. This assumption is of great importance because it eliminates two...
This tutorial model demonstrates the use of brick and prism meshes to mesh thin 3D structures. An identity boundary condition makes sure that the concentration is the same across the interface between the two geometries. Connecting two...
