Solar concentrator/cavity receiver systems can be used to focus incident solar radiation into a small region, generating intense heat which can then be converted to electrical or chemical energy. A common figure of merit in solar thermal power systems is the concentration ratio, or the ... En savoir plus
An electrostatically actuated MEMS resonator is simulated in the time and frequency domains. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. The dependence of the resonant frequency on DC bias is assessed, and frequency domain and transient ... En savoir plus

A plane-wave mode feeds an axisymmetric horn radiating from an infinite baffle toward an open half space. The radius of the waveguide attached to the horn throat is assumed to be fixed, as well as the depth of the horn and the size of the horn mouth attached to the baffle. By varying the ...

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 example demonstrates the usage of current terminal to compute the resistive heating of a busbar. En savoir plus
Mass transport limitations within thin crevices can often result in the local electrochemistry to differ significantly between the crevice opening (mouth) and end (tip), and as a result of the differences in local chemistry, corrosion may occur. This example models crevice corrosion of ... En savoir plus
This example studies a portion of the vascular system of a young child. The aorta and its ramified blood vessels are embedded in biological tissue. The pressure from the moving fluid deforms the blood vessel. The complete analysis consists of two distinct but coupled procedures: a fluid ... En savoir plus
This tutorial model demonstrates the use of dynamic cyclic symmetry with postprocessing on the full geometry. A 3D impeller with eight identical blades can be divided into eight sectors of symmetry. The model computes the fundamental frequencies for the full impeller geometry and ... En savoir plus
