The classical forward problem of geoelectrics (includes electrical resistivity tomography, ERT and earlier techniques as vertical electric sounding, VES) is the calculation of potentials at a given set of electrodes (M,N) while current is injected at other electrodes (A,B) into the ... 詳細を見る

An electron gun must be able to draw a sufficient current and accelerate the electrons to the desired speed. The first part of an electron gun geometry presents unique design challenges because the emitted electron speeds are usually lowest there, and therefore the space charge density ... 詳細を見る

The dielectric shielding boundary condition is meant to approximate a thin layer of material with high relative permittivity compared to its surroundings. This boundary condition is available for electrostatic field modeling. This example compares the dielectric shielding boundary ... 詳細を見る

A Gaussian beam is incident on a 45-degree thin-film stack embedded in glass material prisms. The thin-film stack is designed from alternating high and low refractive index materials. The wave will be refracted at the Brewster angle at each internal interface. Thus, mainly p-polarized ... 詳細を見る

This app allows to calculate the absorption coefficient and surface impedance of a sound absorbers for normal and random incidences. The computed quantities can be used when setting up boundary conditions in a Pressure Acoustics, Frequency Domain model or a Ray Acoustics model. The ... 詳細を見る

This tutorial model shows the setup of a 2D axisymmetric stress analysis, through contact, of a 3D threaded pipe fitting. The example involves synchronizing the 3D Solid Edge® geometry and selections, which specify the faces in contact, with the 2D geometry in COMSOL  ... 詳細を見る

This application uses the Chemical Reaction Engineering Module to study an elementary, exothermic, irreversible reaction in a tubular reactor (liquid phase, laminar flow regime). To keep its temperature down, the reactor uses a cooling jacket with a constant coolant temperature. The ... 詳細を見る

A Fresnel lens can be constructed from a plano-convex lens as a way to reduce the thickness. This model models the collimation property of a Fresnel lens and demonstrates the geometry operation of making a Fresnel lens from a plano-convex lens. 詳細を見る

このアプリは, 電池テストサイクル中の NMC111/グラファイトバッテリセルのセル電圧, セル開放電圧, および内部抵抗を予測するための代理モデル関数の使用方法を示します. 代理関数 (ディープニューラルネットワーク) は, 入力データ値のサブセットに適合されています. 入力データ値は, サイクルの4つのセグメントにおける電流とバッテリセルの初期充電状態の5つを設定できます. 代理関数の評価にかかる計算コストが低いため, ノブを使用して入力値を対話的に組み合わせ, セル電圧と内部抵抗を予測できます. 値の組み合わせを選択したら, ... 詳細を見る

Magnetotellurics is a method for estimating the resistivity profile of the Earth's subsurface using the natural electromagnetic source provided by the ionosphere. This model was defined by Zhdanov et al. in a study published in 1997. In this article, various scientific groups compared ... 詳細を見る
