All integrated circuits (ICs) — especially high-speed devices — produce heat. In today’s dense electronic system layouts, heat sources are many times placed close to heat-sensitive ICs. Designers of printed circuit boards often need to consider the relative placement of heat ... En savoir plus
Continuous mixing is used in process equipment to mix components in a single pass. Compared to batch mixing, this operation has the advantage that the tank filling and emptying steps are eliminated, implying that the process can be run without interruptions. A disadvantage of continuous ... En savoir plus
This tutorial shows how to set up a 3D simulation of rubber injection molding. A phase field method is used to track the interface between the rubber and the displaced air. The rubber is modeled as shear-thinning inelastic non-Newtonian power law fluid with a fluid-consistency ... En savoir plus
A steel billet is quenched in oil from its austenitic state. A 2D axisymmetric model is used to simulate the coupled problem of austenite decomposition, heat transfer, and solid mechanics. During the quenching process, the austenite decomposes into a combination of ferrite, pearlite, ... En savoir plus
This model shows how to set up a simulation of flow through a fractured reservoir. The reservoir includes a discrete fracture network (DFN), where the fractures have a randomized distribution of position, size, orientation and aperture. The model uses the Discrete Fracture Network Add ... En savoir plus
This tutorial model uses a heat sink geometry from the Part Library. The tutorial shows different approaches to heat transfer modeling when studying the cooling of an electronic chip. In the first part, only the solid parts are modeled, while the convective airflow is modeled using ... En savoir plus
A charge exchange cell consists of a region of gas at an elevated pressure within a vacuum chamber. When an ion beam interacts with the higher-density gas, the ions undergo charge exchange reactions with the gas which then create energetic neutral particles. It is likely that only a ...

The flow around the Eppler 387 airfoil is computed with the SST turbulence model both with and without the transition model. The reuslts are compared with experimental values. En savoir plus
This example models flow in a microchannel heat exchanger by coupling a Laminar Flow interface in 3D to a Pipe Flow interface. By the use of the Pipe Flow interface to model the flow in the microchannels the problem size is significantly reduced. This model showcases the Pipe Connection ... En savoir plus
This model performs a topological optimization for a Tesla microvalve. A Tesla microvalve inhibits backwards flow using friction forces rather than moving parts. The design can be optimized by distributing a specific amount of material within the modeling domain. The goal is to maximize ... En savoir plus
