The mutual inductance and induced currents between a single turn primary and twenty turn secondary coil in a concentric coplanar arrangement is computed using a frequency domain model. Each turn of the secondary coil is modeled explicitly. The results are compared against analytic ... 詳細を見る

Including circumferential displacements in a 2D axisymmetric Solid Mechanics interface allows to compute twist and bending deformations. This model determines stress concentration factors for a hollow shaft for load cases of axial extension, torsion, as well as bending, using a ... 詳細を見る

この例では, 水で満たされた貯水池の上に置かれた細い垂直シリンダーを調べます. 空気と水の界面の壁面接着と表面張力により, 水は流路を通って上昇します. 表面張力と壁面接着力は, MEMS デバイスのマイクロ流路を通じて流体を輸送したり, マイクロピペットを使用して少量の流体を測定, 輸送, 配置したりするためによく使用されます. 多孔質媒体を通る多相流や固体壁上の液滴も, 壁面接着力と表面張力が流れのダイナミクスに強く影響する例です. 壁面の接着力を正しくモデル化するには, 境界条件の扱いが重要です. 壁面の速度をゼロに固定すると, ... 詳細を見る

This is a demonstration of how to use the thermodynamics functionality in the COMSOL Multiphysics® software to make flash calculations. A flash calculation is an equilibrium calculation of a system where several species and phases are present at the same time. The system in ... 詳細を見る

In this example, the brittle fracture of a holed plate with a notch is modeled using a phase-field damage model. The geometry of the plate is set up so that a mixed-mode fracture is induced, with dimensions and material properties taken from experimental data. The example shows how to ... 詳細を見る

This is a tutorial example, showing how to work with pretensioned bolts. Various aspects of bolt modeling are explored: Modeling bolts as solids or by beams Connections of beams to solid components Bolts ended by nuts or by internal threads in the attached component Import of bolt and ... 詳細を見る

A strong permanent magnet is placed close to a clamped thin plate made of iron. The magnetic force causes the plate to be deflected. This example studies the plate's elastic deformation and stress. The deformation of the plate has an influence on the distribution of the magnetic field. ... 詳細を見る

This model calculates the eigenfrequencies and mode shapes of an unconstrained cylinder in axisymmetry. The model is taken from NAFEMS Free Vibration Benchmarks. The eigenfrequencies are compared with the values given in the benchmark report. Three different physics interfaces are ... 詳細を見る

This tutorial analyzes the hysteresis of the conductance-gate-voltage (G-Vg) curves of an InAs nanowire FET, using the density-gradient theory to add the effect of quantum confinement to the conventional drift-diffusion formulation, without a large increase of computational costs. The ... 詳細を見る

In this example, a rotor supported on two hydrodynamic bearings is analyzed. An eccentric disk located between the two bearings causes the rotor to whirl. One of the bearings is misaligned with the axis of the rotor. The Beam Rotor with Hydrodynamic Bearing interface in the ... 詳細を見る
