Modeling and simulation is useful for evaluating the feasibility of storing hydrogen underground. In this example of a geological formation, hydrogen is injected through an injection well at a rate of 1 kg/s over a period of 2 years, until it is ready to be extracted and discharged ...

This tutorial model solves for an inductively coupled plasma reactor in a mixture of CF4/O2. The plasma transport, magnetic fields, fluid flow, and heat transfer are solved for fully self-consistently. The oxygen mole fraction of the reactor feed is parameterized. En savoir plus
In this model a plane wave with circular polarization is reflected off an interface between air and glass. The model demonstrates three different ways of defining this problem. The first part shows how to define user-defined port mode fields. The second part uses the predefined circular ... En savoir plus
This model demonstrates an efficient approach to simulating a thin, spherical, large radome using a 2D axisymmetric formulation with cubic discretization. The axisymmetric method captures full 3D behavior for azimuthally symmetric geometries at only a fraction of the computational cost. ... En savoir plus
This model demonstrates how the sun causes 1.75 arcseconds of deflection for rays grazing the sun's surface as observed from the earth. Einstein predicted this value after refining his theory of relativity during World War I. En savoir plus
Tesla microvalves exploit the non-linear nature of inertial flow to create anisotropic flow resistance. They can be used as robust valves owing to their passive working mechanism, but for many applications the diodicity is too low. Two-dimensional simulations and optimization over ... En savoir plus
One of the ways we can simplify and reduce the size and computational complexity of a finite element model is by using any symmetries present in a model. In this entry, you can find three practical examples highlighting how to exploit symmetries in RF or wave optics modeling. They all ... En savoir plus
In acoustofluidics, acoustics is used to manipulate particles and fluids in microfluidic devices. This model demonstrates the phenomena of the inhomogeneous acoustic body force and how it can move a fluid with an inhomogeneous density due to a solute. The model is of a 2D cross section ...
