Tutorials in this series deal with creating and manipulation of boundary layer meshes. In these tutorials you will learn how to set up a boundary layer mesh and modify the settings for an automatically created boundary layer mesh. For physics-controlled meshing a boundary layer mesh is ... En savoir plus
This alternative version of the Tubular Reactor app demonstrates how computational speed can be significantly increased by using a surrogate model instead of a full finite element model. A surrogate model is a simplified, computationally efficient approximation of a more complex and ... En savoir plus
In this example, a torque is applied to the inner edge of a circular annulus-shaped membrane while the outer edge is fixed, resulting in membrane wrinkling. The wrinkling membrane model avoids the equilibrium instability that would be produced by the compressive stresses. The effect of ... En savoir plus
This tutorial model presents a study showing the transient negative mobility and the negative differential conductivity effects in xenon. The stationary and time dependent Boltzmann equation in the two-term approximation is used to compute the electron energy distribution function. ... En savoir plus
This tutorial model is kindly provided by Riccardo Vietri, James Ransley and Andrew Spann at Veryst Engineering, LLC. Piezoelectric micropumps are frequently used in medical applications because of their ability to precisely control the metering of very small volumes of fluids or gases. ... En savoir plus
This model simulates atmospheric galvanic corrosion of a busbar, which includes a copper flange, an aluminum alloy flange in contact with a zinc nut and bolt. The Secondary Current Distribution interface is used to solve for the electric potential in electrode domain and Current ... En savoir plus
In this example, drug-release from a biomaterial matrix to damaged cell tissue is modeled. Specifically, a nerve guide delivers a regenerating drug to damaged nerve ends. The model involves detailed drug release kinetics, with rate expressions handling drug dissociation/association ... En savoir plus
The Ahmed body represents a simplified, ground vehicle geometry of a bluff body type. Its shape is simple enough to allow for accurate flow simulation but retains some important practical features relevant to automobile bodies. This model describes how to calculate the turbulent flow ... En savoir plus
This model simulates a plasma at medium pressure (2 torr) where the plasma is still not in local thermodynamic equilibrium. At low pressures the two temperatures are decoupled but as the pressure increases the temperatures tend towards the same limit. En savoir plus
This example models the transient heating, and final temperature, of a disc brake of a car in brake-and-release sequence. It is important to model the transient heating and the following convective cooling to determine the minimum interval between a series of similar brake engagements. ... En savoir plus
