This example simulates 3D unsteady laminar flow past a cylinder in a channel. The inflow velocity profile is time-varying. The lift and drag coefficients are computed, and results show good agreement with those published in the literature. En savoir plus
This model simulates a temperature profile in a number of cells and cooling fins in a liquid-cooled battery pack. The model solves in 3D and for an operational point during a load cycle. A full 1D electrochemical model for the lithium battery calculates the average heat source. En savoir plus

This model demonstrates the analysis of lightning surges on high voltage transmission line towers. Lightning carrying a current of 10 kA struck one of the tower's shielded wires. The induced voltage at the three-phase conductors are computed. Some highlights of this model: Perform ... En savoir plus
Interfacial failure or delamination in a composite material can be simulated with a cohesive zone model (CZM). A key ingredient of a cohesive zone model is a traction-separation law that describes the softening in the cohesive zone near the delamination tip. This example shows the ... En savoir plus
This tutorial demonstrate the use of a Cross Grating feature in an échelle spectrograph. A cross grating is a periodic surface with two directions of periodicity. In this model the cross grating is used in high order in one direction and in first order in the orthogonal ("cross") ... En savoir plus
This model shows how a flow model can be coupled to a process control mechanism. Controlling application parameters according to other application parameters is important within process engineering. Most control mechanisms use the data at a wall or an outlet to control inlet ... En savoir plus
This model presents the static field modeling of an outward flux focusing magnetic rotor using permanent magnets. This magnetic rotor is also often called a Halbach rotor. The use of permanent magnets in rotatory devices such as motors, generators and magnetic gears is increasing. The ... En savoir plus
This models pressure-dependent heating of 4 inch wafer on unipolar electrostatic chuck. Wafer sits on top of ring with electrostatic force holdong down wafer to counter upward pressure from gas flowing in gap between wafer and chuck surface. It is a problem involving 4 coupled physics ... En savoir plus
An eigenfrequency study is used to find the resonance frequency and threshold gain for an oxide-confined, GaAs-based, vertical-cavity surface-emitting laser (VCSEL). The simulations are performed in two steps. A regular eigenfrequency analysis is first performed, to find good initial ... En savoir plus
