This tutorial model illustrates how to analyze the thermal effects of the sun as an external radiative source and considers wavelength-dependent surface emissivities. Specifically, the model features two coolers containing beverage cans that are exposed to ambient conditions and a beach ... En savoir plus
At the resonance frequency, the capacitive coupling between the turns causes the impedance of a coil to transition from inductive to capacitive. This application analyzes the resonance of a 5 turn spiral coil of copper equipped with a thin epoxy varnish insulation layer. The capacitive ... En savoir plus
These examples demonstrate how to compute the total reflection, transmission, and absorption of light when a plane wave, at optical wavelengths, is incident upon a dielectric slab with a thin metal coating. Three examples are included that show: An optically flat slab A slab with a ... En savoir plus
This example is a benchmark problem for simulating phase change in porous media. It studies the melting process of an ice inclusion within porous media and therefore demonstrates how to couple Darcy's Law with the Heat Transfer in Porous Media interface including phase change. En savoir plus
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 ... En savoir plus
Two embedded optical waveguides in close proximity form a directional coupler. The cladding material is GaAs and the core material is ion-implanted GaAs. The waveguide is excited by the two first supermodes of the waveguide structure - the symmetric and antisymmetric modes. Two numeric ... En savoir plus
Metal hydride tanks offer safe hydrogen storage, thanks to their low reactivity, and a relatively high hydrogen density. When developing metal hydride hydrogen tank designs, modeling and simulation is useful for optimizing operating conditions, such as gas composition, pressure, and ... En savoir plus
This example illustrates the principle of electrochemical polishing. The simplified 2D model geometry consists of two electrodes and an intermediate electrolyte domain The positive electrode has a protrusion, representing a surface defect. The purpose of the model is to examine how this ... En savoir plus
This model demonstrates how to simulate a piezoelectric transducer as both a sound transmitter and a receiver in a well logging setup. Other applications of this setup are, for example, in the field of nondestructive testing. A transmitting transducer is connected to an electrical ... En savoir plus
This example is a model of a continuous casting process. Liquid metal is poured into a mold of uniform cross section. The outside of the mold is cooled and the metal solidifies as it flows through. When the metal leaves the mold, it is completely solidified on the outside, but still ... En savoir plus
