Dieses Tutorial-Modell veranschaulicht, wie die thermischen Auswirkungen der Sonne als externe Strahlungsquelle analysiert werden können und berücksichtigt wellenlängenabhängige Oberflächenemissionen. Das Modell enthält zwei Kühlboxen mit Getränkedosen, die den Umgebungsbedingungen ... Mehr lesen
A stationary 3D model of a generic fuel cell cathode describing the mass fraction distribution of oxygen, water, and nitrogen, as well as the current distribution. The model uses Darcy's Law to describe convection, and couples this to Maxwell-Stefan diffusivities to also describe mass ... Mehr lesen
Large FEM simulations can be costly and, if repeated simulations are needed, it can be beneficial to use reduced-order models (ROMs). ROMs are typically valid only in the vicinity of their design conditions and have lower accuracy, but the simulation time is significantly shorter. The ... Mehr lesen
In this example, the homogenized elastic and viscoelastic properties of a particulate composite are computed based on the individual properties of elastic particles embedded in a viscoelastic matrix. Periodic boundary conditions are applied to a unit cell of the particulate composite ... Mehr lesen
Developments in the last decade have made circuit quantum electrodynamics (cQED) the leading architecture for quantum computation. cQED is the solid-state version of cavity QED, which studies the basic light-matter interactions at the quantum level. This model examines one of the main ... Mehr lesen
Chemical vapor deposition (CVD) allows a thin film to be grown on a substrate through molecules and molecular fragments adsorbing and reacting on a surface. This example illustrates the modeling of such a CVD reactor where triethyl-gallium first decomposes, and the reaction products ... Mehr lesen
This example models the behavior of soil during a tunnel excavation. The surface settlement and the width of the plastic region around the tunnel are important parameters needed to predict required reinforcements during the excavation. Two study steps are used. The first study computes ... Mehr lesen
Scientists use the SAR (specific absorption rate) to determine the amount of radiation that human tissue absorbs. This measurement is especially important for mobile telephones, which radiate close to the brain. The model studies how a human head absorbs a radiated wave from an antenna ... Mehr lesen
This model shows how shape optimization can be used to design an acoustic demultiplexer. A demultiplexer is a data distributing device, in this case it will distribute acoustic energy. The geometry consists of a circular domain with one input port and two output ports. The domain has the ... Mehr lesen
The GEC cell was introduced by NIST in order to provide a standardized platform for experimental and modeling studies of discharges in different laboratories. The plasma is sustained via inductive heating. The Reference Cell operates as an inductively-coupled plasma in this model. This ... Mehr lesen
