This tutorial shows how to simulate coupled heat and moisture transport in an insulated roof structure, made of a load bearing and an insulation layer. The thermal insulation is facing the interior and there is a moisture barrier facing the exterior. The load bearing is capillary active ... En savoir plus
To understand the risk of coagulation and blood clot formation in an abdominal aortic aneurysm (AAA), modeling and simulation can be used to study the blood flow through the AAA. In this example, blood is modeled as an Oldroyd-B fluid. While this is a generic example, if instead using ... En savoir plus
Active aerodynamics systems actuate components on a vehicle dynamically to improve fuel efficiency, optimize cooling, and enhance stability. A drag reduction system (DRS) is an example of an active aerodynamic technology, which is often used in Formula 1® cars to overtake other cars ... En savoir plus
This model analyzed the ALD deposition process of alumina film on the surface of a U-shaped structure. In this process, gaseous precursors are sequentially introduced to the reaction chamber and sequentially undergo a series of adsorption and chemical reactions on the surface. The ... En savoir plus
This benchmark model computes the pressure in a system of outgassing pipes with a high aspect ratio. The results are compared with a 1D simulation and a Monte-Carlo simulation of the same system from the literature. En savoir plus
This model computes the particle flux, number density and pressure on the surface of a plate that rotates in a highly directional molecular flow. The results obtained are compared with those from other, approximate, techniques for computing molecular flows. En savoir plus
This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic step bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. En savoir plus
This example shows how to model tissue ablation through applying RF radiation. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Study Radiofrequency Tissue Ablation Using Simulation". En savoir plus
This model demonstrates how to use the built-in shape optimization functionality to improve the performance of a plate heat exchanger. The optimization reduces the path immediately in front of the inlets and outlets to increase the length of typical streamlines. This leads to a improved ... En savoir plus
This model shows how to define a frequency-domain analysis of heat transfer. The 3-omega method uses the Cahill's equation to approximate the thermal conductivity of a sample from the measured temperature of a metal strip placed on top of it and subject to oscillating heating. The 2D ... En savoir plus
