In massive forming processes like rolling or extrusion, metal alloys are deformed in a hot solid state with material flowing under ideally plastic conditions. Such processes can be simulated effectively using computational fluid dynamics, where the material is considered as a fluid with ... 詳細を見る
A Chladni plate is a metal plate that is covered in sand and subjected to vibrations. At certain frequencies, the vibrations produce standing waves, resulting in sand patterns formed on the plate. The vibrations are either formed from a violin bow at the side of the plate or a wave ... 詳細を見る
A magnetic brake consists of a permanent magnet, which induces currents in a rotating copper disk. The resulting eddy currents interact with the magnetic flux to produce Lorentz forces and subsequently a braking torque. This 3D problem is solved using a stationary formulation for the ... 詳細を見る
In this application, a solution is pumped through a catalytic bed where a solute species reacts as it gets in contact with the catalyst. The purpose of this example is to maximize the total reaction rate for a given total pressure difference across the bed by finding an optimal catalyst ... 詳細を見る
アンテナクロストーク, すなわちコサイト干渉は, 複数のアンテナを単一の大型プラットフォーム上で使用する場合に問題となります. このモデルでは, 航空機の胴体に設置された受信アンテナの異なる構成におけるSパラメーター解析により, VHF周波数における2つの同一アンテナ間の干渉を解析します. 送信アンテナの2次元および3次元の遠方場放射パターンを計算し, 航空機表面の明るい領域と影の領域も可視化します. 詳細を見る
This is a model from electric impedance tomography, a method of imaging the interior permittivity distribution of a body by measuring current and voltage at the surface. This model demonstrates how the shape and placement of figures with different material properties inside a closed ... 詳細を見る
Optical lenses of millimeter size cannot easily be analyzed with the Electromagnetic Waves, Frequency Domain interface on standard workstations due to the large number of finite element mesh elements required. This model explains how the Electromagnetic Waves, Beam Envelopes interface ... 詳細を見る
Electronic equipment often has to be certified to function after having been subjected to a specified shock load. In this example, the effect of an 50g 11ms half sine shock on a circuit board is investigated using response spectrum analysis. The results are compared with a time domain ... 詳細を見る
Topology optimization of the Navier-Stokes equations is encountered in different branches and applications, such as in the design of ventilation systems for cars. A common technique applicable to such problems is to let the distribution of porous material vary continuously. In this ... 詳細を見る
This model describes a modal analysis of a crankshaft. The pistons’ reciprocating movement is transferred to the crankshaft through connecting rods by means of crankshaft throws. The forces, torques, and bending moments, which are highly variable both in time and space, subject the ... 詳細を見る
