Electroporation is a technique where a localized electric field is used to generate nanometric pores in cell membranes, improving the cell permeability for ions and pharmaceuticals. This model shows the electroporation of a spherical cell by means of a nanosecond electric pulse. The ... 詳細を見る

This is a model of a moving-coil loudspeaker where a lumped parameter analogy represents the behavior of the electrical and mechanical speaker components. The Thiele-Small parameters (small-signal parameters) serve as input to the lumped model, which is represented by an Electric Circuit ... 詳細を見る

This tutorial illustrates the use of the connecting features in the Heat Transfer in Solids and Heat Transfer in Shells interfaces, to couple them to a Lumped Thermal System interface. The results obtained with the solid and shell models are compared. 詳細を見る

Headphones are closely coupled to the ear, and so it is not possible to measure their sensitivity in a classical acoustic free-field setup used for loudspeakers. The measurement requires the use of artificial heads and ears to accurately represent the usage conditions. This model shows ... 詳細を見る

This model demonstrates how to use the Control Function feature to perform shape optimization on a rectangular horn for an improved on axis response. The results of the initial design are exported to a new component via a Filter dataset. Further, the off-axis spatial response is improved ... 詳細を見る

Magnetic resonance imaging (MRI) systems generate a magnetic flux density (B-field) to create images. Providing a homogeneous field distribution within a birdcage coil is a key factor for improving the quality of the scanned data. A homogeneous magnetic field can be found through ... 詳細を見る

At the electrode-electrolyte interface, there is a thin layer of space charge in a diffuse double layer. This may be of interest when modeling devices such as electrochemical capacitors and nanoelectrodes. This tutorial example shows how to couple the Nernst-Planck equations to the ... 詳細を見る

This model shows how to simulate the complex discharge physics behind the well-known electrostatic discharge (ESD). The model connects the Electrical Discharge interface with the Circuit interface to simulate how ESD current is generated when a human hand touches metal. 詳細を見る
