This example demonstrates how to import a bitmap which can be used to simulate an image using ray tracing. The example is based on the Double Gauss Lens tutorial from the Ray Optics Module Application Library. The first study has been modified so that the Spot Diagram "auto-focus" tool ... 詳細を見る

Impressed current cathodic protection is a commonly employed strategy to mitigate the ship hull corrosion where an external current is applied to the hull surface, polarizing it to a lower potential. In this model, the effect of propeller coating on the current demand is demonstrated. 詳細を見る

この非従来型の多孔質媒体流れモデルは, 多孔質媒体の隙間におけるクリープ (ストークス) 流を利用します. このモデルは, カリフォルニア大学サンタバーバラ校の Arturo Keller 氏, Maria Auset 氏, Sanya Sirivithayapakorn 氏が行った細孔スケールの流れ実験に基づいています. モデルに使用されている形状は, 走査型電子顕微鏡画像から作成されました. この例では, Keller 氏, Auset 氏, Sirivithayapakorn 氏による 2D マイクロ媒体画像の1つを使用し, ... 詳細を見る

Linear motors are used in many applications in need of translational motion. Typical characteristics of linear motor designs are high precision or quick acceleration. This model investigates a synchronous motor with three-phase winding on the stationary part and permanent magnets on the ... 詳細を見る

Échelle spectrographs are commonly used in astronomy for high-resolution analyses of stellar atmospheres and for precision Doppler velocimetry. This tutorial simulates a "white pupil" form of this instrument. It makes use of several parts from the COMSOL Part Library and demonstrates the ... 詳細を見る

An eigenfrequency study is used to find the resonance frequency and threshold gain for an oxide-confined, GaAs-based, vertical-cavity surface-emitting laser (VCSEL). The simulations are performed in two steps. A regular eigenfrequency analysis is first performed, to find good initial ... 詳細を見る

This model calculates the DC characteristics of a simple MOSFET. The drain current versus gate voltage characteristics are first computed in order to determine the threshold voltage for the device. Then the drain current vs drain voltage characteristics are computed for several gate ... 詳細を見る

The Free Molecular Flow interface, available in the Molecular Flow Module, is an efficient tool for modeling extremely rarefied gases when the gas molecules move much faster than any geometric entities in the domain. For turbomolecular pumps, in which the blades move at speeds comparable ... 詳細を見る

This example shows how to compute deformations caused by secondary creep in a turbine stator blade. The creep rate is highly influenced by temperature, and the deformation and stress relaxation is thus controlled by the temperature field. 詳細を見る

This tutorial drives a capacitively coupled plasma with an L-type matching network at high and low powers. At low power, where the harmonics in the current are low, prefect matching is obtained at the chosen power value. Sweeps over power, frequency, and pressure are performed and their ... 詳細を見る
