Using a Fluid-Solid Interaction multiphysics interface, the behavior of a spring-loaded ball check valve is studied under varying functional and reverse flow. The fluid force acting on the ball opens the valve at the opening pressure. In the case of a reversed pressure, the ball comes ... 詳細を見る

This model shows how to compute the anchor loss limited quality factor of a diamond disc resonator. The resonator is anchored to the substrate by a polysilicon post and power is transmitted to the substrate through the post. A perfectly matched layer is used to represent the essentially ... 詳細を見る

ヘルムホルツコイルは, 半径1つ分離れた2つの同一の円形コイルを平行に並べたものであり, 両方のコイルに電流が同じ方向に流れるように巻かれています. この巻き方により, コイル間に均一な磁場が生じ, 主な成分は2つのコイルの軸に平行になります. ヘルムホルツコイルの用途は, 地球の磁場を打ち消すことから, 実験やそれを必要とするアプリケーション用の磁場の生成まで多岐にわたります. ヘルムホルツ磁場の生成は, アプリケーションに応じて, 静的, 時間変動 DC, または AC になります. 詳細を見る

This example presents a homogenized model of a corrugated sheet based on a unit cell approach. The numerically obtained equivalent stiffness matrices are compared with various analytical models. Two corrugation profiles, trapezoidal and round, are considered in this example. 詳細を見る

磁場中の鉄球は, 磁場が透過性材料と相互作用する効果を示す優れた教科書的な例です. このチュートリアルシリーズは, COMSOL を用いた電磁効果の数値モデリングの入門として設計されています. このシリーズでは, 静的背景磁場と 60 Hz, 20 kHz, 13.56 MHz の3つの時間変動磁場からなる4つの異なる背景磁場レジームを解析します. これらのレジームはそれぞれ独自の挙動と前提を持ち, 異なるモデリング手法を用いています. これらのモデルはすべて, 入門モデルを出発点として, 任意の順序で完成させることができます. 詳細を見る

In a cooling system, a microelectronic component has been identified as the critical link. Since the power is repeatedly switched on and off, the component is subjected to thermal cycling. As a results a crack grows through a solder joint and disconnects the chip from the printed circuit ... 詳細を見る

In this example, the mechanical impact of a golf club hitting a golf ball is studied. The contact between the two parts is modeled using a viscous penalty formulation to stabilize the dynamic event. To properly model the large deformation, the golf ball is defined using a hyperelastic ... 詳細を見る

This model is an introduction to defining and verifying a satellite orbit, and computing the solar, albedo, and Earth infrared thermal loads. A 1U CubeSat is in a circular orbit at 400km altitude, inclination of 50°, and longitude of ascending node of 0°. The satellite is rotating slowly ... 詳細を見る

A typical capacitor is composed of two conductive objects with a dielectric in between them. A voltage difference applied between these objects results in an electric field between them. This electric field exists not just directly between the conductive objects, but extends some ... 詳細を見る

This example uses asymptotic techniques to study the radar cross-section (RCS) response of a conductive sphere. The selected physics interface transforms the incident plane-wave field on the boundaries to the far-field using the Stratton–Chu formula. The computed results are compared to ... 詳細を見る
