In this tutorial the acoustic behavior of a duct or waveguide with a right angled bend is analyzed. The model uses port boundary conditions at the inlet and outlet. The ports can capture and treat non-plane propagating modes in waveguides, extending the analysis above the first cutoff ... 詳細を見る

Small heating circuits find use in many applications. For example, in manufacturing processes, they heat up reactive fluids. The device in this tutorial consists of an electrically resistive layer deposited on a glass plate. The layer results in Joule heating when a voltage is applied to ... 詳細を見る

This model shows how to perform a submodeling analysis in order to evaluate structural stress. Using a submodel helps to compute the results in a refined geometry detail while applying loads and constraints in the global model. 詳細を見る

A gearbox is used to transfer power from an engine to its associated wheels or cogs, which can result in radiating noise to the surroundings. This is due to the transmission of undesired lateral and axial forces on the bearings and housing, while transmitting power from one shaft to the ... 詳細を見る

In this tutorial model, a step thrust bearing is topology optimized to maximize the bearing capacity. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be ... 詳細を見る

UHF RFID tags are widely used for identifying and tracking animals. This model simulates a passive radio-frequency identification (RFID) tag for the UHF frequency range. With respect to the chip transponder’s complex impedance, a reflection coefficient is computed. This is done using an ... 詳細を見る

A plane electromagnetic wave propagating through free space is incident at an angle upon an infinite dielectric medium. This model computes the reflection and transmission coefficients and compares to the Fresnel equations. 詳細を見る

This 3D model of a nanowire MOSFET employs the density-gradient theory to add the effect of quantum confinement to the conventional drift-diffusion formulation, without requiring excessively high computational costs. The oxide layer is simulated explicitly with geometric domains, and ... 詳細を見る

This tutorial model shows how to import a 3D scanned geometry of a human head and torso and compute the head related transfer function (HRTF). The scan is imported as a .stl file and converted into a COMSOL geometry. The HRTF is computed using the reciprocity principle, locating the ... 詳細を見る
