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 ... En savoir plus
The eigenfrequencies of a rotating blade are studied in this benchmark. It shows how stress stiffening and the combined effect from stress stiffening and spin softening affects the fundamental eigenfrequency. High rotational speed in rotating machineries can result in centrifugal forces ... En savoir plus
This model shows how to compute the AC characteristics of a MOSFET. Both the output conductance and the transconductance are computed as a function of the drain current. En savoir plus
This model studies the natural frequencies of a pre-tensioned string using the 2D Wire interface. This is an example of “stress stiffening”; in fact the transverse stiffness of wire elements is directly proportional to the tensile force. Strings made of piano wire have an extremely high ...

In his example, the lowest natural frequency of a 3D bracket are maximized using shape optimization. En savoir plus
Corrugated circular aperture (conical) horn antennas are popularly used as feed horns for dish reflector antennas due to their low sidelobes and cross-polarization level. The excited TE mode from a circular waveguide passes along the corrugated inner surface of a circular horn antenna, ... En savoir plus
This model approximates 3D spherical transport using a 1D model. Many models of industrial-transport problems allow the assumption that the problem is spherically symmetric. This assumption is of great importance because it eliminates two space coordinates to result in a 1D problem that ... En savoir plus
Graphene, carbon atoms arranged in a two-dimensional hexagonal lattice has sparked tremendous research and application interests since its experimental discovery about two decades ago. Besides being ultrathin, this material exhibits a plethora of interesting properties, including high ... En savoir plus
This tutorial is intended as a simple example showing how to model piezoelectric devices using the layered shell functionality. Two cases of material orientation are investigated. In the first case, the pole axis is normal to the shell surface, which results in a change in thickness of ... En savoir plus
A circular waveguide filter is designed using a 2D axisymmetric model. Six annular rings added to the waveguide form circular cavities connected in series, and each cavity cutoff frequency is close to the center frequency of the filter. The simulated S-parameters show a bandpass ... En savoir plus
