This example demonstrates how to optimize the thickness of a microelectromechanical systems (MEMS) mirror coating material for maximum reflectivity. To reduce the simulation time, a Layered Impedance Boundary Condition is used to model the thin coating material on top of the metallic ... 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

A fuel cell stack operates at temperatures just below 100 °C, which means that it has to be heated at start-up. The fuel cell stack consists of unit cell of anode, membrane, and cathode connected in series through bipolar plates. This study presents a model that couples the thermal and ... 詳細を見る

In the surface acoustic waves industry different crystal cuts of piezoelectric materials are used, e.g. 128ᵒ YX LiNbO3, AT&ST quartz, 42ᵒ YX LiTaO3, etc. Direct data isn’t available for all cuts. The standard approach is to use the so-called Euler angle rotation. COMSOL supports it ... 詳細を見る

This example showcases a helical planetary gear train composed of a sun gear, ring gear, carrier, and five planet gears. Three cases are analyzed by in turn fixing the ring gear, sun gear, and carrier. For each configuration, a transient multibody analysis is performed to determine the ... 詳細を見る

This model simulates a GaN based light emitting diode. The emission intensity, spectrum, and quantum efficiency are calculated as a function of the driving current. Direct radiative recombination across the band gap is modeled, as well as non-radiative Auger and trap-assisted ... 詳細を見る

Carbon dioxide in aqueous solution is highly corrosive and can cause significant damage to steel designs. Such conditions arise in pipes used in a variety of applications, especially within the petrochemical industry. In this tutorial example, turbulent flows consisting of carbon ... 詳細を見る

This model computes the trajectory of an ion in a uniform magnetic field using the Newtonian, Lagrangian and Hamiltonian formulations available in the Mathematical Particle Tracing interface. 詳細を見る

This model exemplifies the basic principles of crevice corrosion and how a time-dependent study can be used to simulate the electrode deformation. The model is in 2D and the polarization data for the corrosion reaction is taken from a paper by Absulsalam and others. The model and the ... 詳細を見る

This model illustrates how to compute the torque of a three-phase squirrel-cage induction motor at various speeds. In the example the torque is computed by averaging the results from simulations performed on 2D cross sections at several locations along the induction motor. The 3D ... 詳細を見る
