This example shows how to implement a stress dependent material model. The Young's modulus changes based on the stress value. Mehr lesen
This example was originally formulated by Albert Witarsa under Professor Bruce Finlayson’s supervision at the University of Washington in Seattle. It was part of a graduate course in which the assignment consisted of evaluating the potential of patents in the field of microfluidics ... Mehr lesen
The capability to alter the polarization of light is crucial to a wide variety of optical devices. For example, the polarization of light has a significant effect on the performance of optical isolators, attenuators, and beam splitters. By assigning a specific polarization to light, most ...

A Fresnel rhomb is a prism that uses total internal reflection to manipulate the polarization of light. In this example, light in the prism is internally reflected at an angle of incidence that induces a 45-degree phase delay between s- and p-polarized radiation. By subjecting the light ... Mehr lesen
Due to its high capacity, silicon (Si) is often added to graphite in the negative electrode of lithium-ion batteries. Silicon–graphite blended electrodes may exhibit significant thermodynamic voltage hysteresis (“path dependence”) because the equilibrium potential of the lithium–silicon ... Mehr lesen
A circular waveguide filter is designed using a 2D axisymmetric model. Six annular rings added to the waveguide form circular cavities connected in series, and each cavity cutoff frequency is close to the center frequency of the filter. The simulated S-parameters show a bandpass ... Mehr lesen
A fuel cell unit cell is modeled using the full Butler-Volmer expression for the anodic and cathodic charge transfer reactions. The anodic and cathodic overpotentials depend on the local ionic and electronic potentials, which are obtained from the charge balance equations for ionic and ... Mehr lesen
In this tutorial, the eigenmodes and eigenfrequencies of an air bubble in water is modeled and compared with analytical solutions. The effects of surface tension is included and allows to model both the pulsating mode and the surface modes of the bubble. Lastly, the effect of the ... Mehr lesen
This model demonstrates how to compute the volumetric fluence rate in an ultraviolet (UV) reactor. The geometry is the annular fluid region surrounding a cylindrical lamp. The effect of reflection at the reactor walls on the radial fluence rate distribution is considered. Mehr lesen
This model uses the discrete-ordinates method (DOM) to analyze the radiative heat transfer in a utility boiler with internal obstacles. DOM is one of the most useful radiation models for prediction of radiative heat fluxes on the furnace walls of a combustion chamber. With this model, ... Mehr lesen
