This tutorial explores the current distribution in a low-temperature PEMFC when using serpentine-based flow field patterns. The cell is operated in counter-flow mode so that the oxygen and hydrogen inlet flow streams are located at opposite sides. Relatively dry inlet gas compositions ... En savoir plus
In this 2D tutorial, a test sample consists on one side of an isotropic material and on the other side of a heterogeneous anisotropic material (a transverse anisotropic zinc crystal). Elastic waves in the sample are excited by a point-like force. The model is solved with the Elastic ... En savoir plus
This tutorial model presents a study of a negative corona discharge in dry air at atmospheric pressure in a point-to-plane configuration. An elliptical electrode with millimeter dimensions creates a high intensity electric field where the corona discharge occurs. A ground plane is placed ... En savoir plus
This tutorial demonstrates how an electrical circuit model of a MEMS resonator can be derived using the Parameter Estimation feature. The model is a modified Butterworth-Van Dyke circuit created using the Electrical Circuit interface and represents a Thin-Film Bulk Acoustic Resonator ... En savoir plus
This model demonstrates the analysis of lightning surges on high voltage transmission line towers. Lightning carrying a current of 10 kA struck one of the tower's shielded wires. The induced voltage at the three-phase conductors are computed. Some highlights of this model: Perform ... En savoir plus
In this verification example, forced random vibrations of a simply-supported deep beam are studied. The beam is loaded by a distributed force with a uniform power spectral density (PSD). The output PSD is computed for the displacement and bending stress response. The computed values are ... En savoir plus
A Fabry-Perot resonator is one of the fundamental optical devices and has a broad range of applications. A few examples are that it can be used to measure length, frequency/wavelength or to filter specific spatial modes. This model uses the Beam Envelopes Interface in the bidirectional ...

Patch antennas are becoming more common in wireless equipment, like wireless LAN access points, cellular phones, and GPS handheld devices. The antennas are small in size and can be manufactured with simple and cost-effective techniques. Due to the complicated relationship between the ... En savoir plus
Plasma discharges containing chlorine are commonly used to etch semiconductors and metals in microelectronics fabrication. This tutorial model studies chlorine plasma discharges using a global (volume-averaged) diffusion model. Global diffusion models can run simulations in a fraction ... En savoir plus
Portal Cranes are common when handling heavy loads. In this example, the Beam interface is used to compute the stresses in a portal crane designed for lifting 15 tons. Three load cases are considered: self weight, payload, and thermal expansion on a hot summer day. An internal hinge ... En savoir plus
