This example is an extension of a model used to study the vibration and noise in a 5-speed synchromesh gearbox in a manual transmission vehicle. In this version of the model, a detailed representation of a roller bearing is used instead of hinge joints with elastic stiffness. First, the ... En savoir plus
A spherical water-rich load (potato) is placed on the rotating glass tray of a microwave oven some distance from the center of rotation. 1 kW of 2.45 GHz microwave power is applied via a waveguide feed. The plate rotates at 9 degrees per second. The heat transfer model involves the ... En savoir plus
This benchmark demonstrates how to use the Beam interface in the Structural Mechanics Module. It calculates the deformation, section forces, and stresses in a cantilever beam as well as a number of eigenfrequencies. It also illustrates how to use the Beam Cross Section interface to ...

In this tutorial model, the far-field radiation pattern of a dipole antenna is computed in a 2D axisymmetric model component. Then, in a separate 3D model component, a ray is released using the far-field radiation pattern to initialize the ray's intensity, polarization, and phase. En savoir plus
The Gregory-Maksutov telescope is a simple catadioptric telescope comprising a spherical corrector lens and a spherical primary mirror. In this example the corrector lens and mirror are formed using the 'Spherical Lens 3D' and 'Spherical Mirror 3D' parts respectively from the Ray Optics ... En savoir plus
Electromagnetic waves that are confined to propagate along a surface, such as surface plasmon polaritons (SPPs), are of great research interest due to their potential applications in nanoscale manipulation of light. This model demonstrates how to set up a simulation of the propagation ... En savoir plus
This tutorial model analysis of a microstrip patch antenna shows how to couple the finite element method (FEM) to the boundary element method (BEM) for evaluating the field outside the FEM computational domain.

This is a benchmark model for the 2D axisymmetric formulation of the Electromagnetic Waves, Frequency Domain interface that is available with the RF Module. The problem is to find the resonant frequencies and fields inside an axisymmetric cavity with rectangular cross-section and ... En savoir plus
Tubular reactors are often used in continuous large-scale production, for example in the petroleum industry. One key design parameter is the conversion, or the amount of reactant that reacts to form the desired product. In order to achieve high conversion, process engineers optimize the ... En savoir plus
At the resonance frequency, the capacitive coupling between the turns causes the impedance of a coil to transition from inductive to capacitive. This application analyzes the resonance of a 5 turn spiral coil of copper equipped with a thin epoxy varnish insulation layer. The capacitive ... En savoir plus
