Inductive devices experience capacitative coupling between conductors at high frequencies. Modeling this phenomenon requires that you describe electric fields that have components both parallel with and perpendicular to the wire. This consideration might lead to the conclusion that a 3D ... 詳細を見る

This model shows a setup of two parallel wires with a constant current running through both. Their cross-sections are successively reduced until a set force per unit length is reached. 詳細を見る

This tutorial example shows how to use the Electric Currents in Shells interface together with Magnetic Field interface to compute the resistance and inductance of a planar PCB coil in the stationary regime. 詳細を見る

This tutorial shows how you can use the Electromechanics interface in COMSOL's MEMS Module to model Electrostriction. Electrostrictive materials (e.g. PMN-PT) exhibit nonlinear strain as a function of electric field. This 2D axisymmetry model uses a parametric sweep of voltage to ... 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

In this benchmark example, a semi-elliptical crack at the inner surface of a cylinder is studied. The inside of the cylinder and the crack faces are subjected to a pressure load. The J-integral is calculated along the crack front, and the stress intensity factor is then compared with the ... 詳細を見る

Recovery of precious metals in recycling of electronics, or extraction from ore, is usually performed through leaching of the metal into an aqueous phase. Precious metals require the use of an oxidant, and often, a complexant. In the case of gold, the cyanide anion (CN-) forms a soluble ... 詳細を見る

The bidirectional formulation of the Beam Envelopes interface can be used not only for counter-propagating wave simulations but also for waves propagating to up to two directions. In this model, an almost collimated Gaussian beam is excited at the left boundary and exhibits total ... 詳細を見る

This model demonstrates how to use the Magnetic Fields, Currents Only interface together with the Stationary Source Sweep with Initialization study to compute the inductance matrix of PCB coils with a number of 12. 詳細を見る

The example Stiffness Analysis of a Communication Mast’s Diagonal Mounting in the COMSOL Multiphysics Model Library shows how you can modify a 3D CAD model to improve its performance. In that case, the applied changes were based solely on the analyst’s experience with similar structures. ... 詳細を見る
