Polymer hydrogels consist of a crosslinked network of long-chained polymers that has imbibed a large number of solvent molecules. Such materials are used in many biomedical applications, such as targeted drug delivery, tissue engineering, and stimuli-sensitive actuators. This benchmark ... En savoir plus
This model simulates the propagation of two frequency bands in a photonic crystal with three ports. The crystal is initially symmetric, so that the two frequency bands are directly equally to either output port. The model optimizes the position of the pillars in order to make the two ...

This tutorial model shows how to model a structure using both shells and solids, and how to create the transition between them. Results are compared between the shell solution and the full 3D solution, and the effects of the transition are highlighted. En savoir plus
This benchmark model simulates a graded heterojunction using the thermionic emission formulation for the charge transfer over the junction. It shows the additional contribution to the current density from the quantum tunneling effect across the potential barrier, using the WKB ... En savoir plus
This model calculates the current and charge characteristics of a floating gate Electrically Erasable Programmable Read-Only Memory (EEPROM) device. A stationary study demonstrates the effects of varying the charge stored on the floating gate by computing Current-Voltage curves as a ... En savoir plus
This example provides a walkthrough on how to simulate the basic radiated emission of a printed circuit board and its immunity response from outside noise. First, when one of the microstrip lines is excited, the crosstalk to an adjacent printed line and the radiated field, through an ... 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
Micromixers can either be static or dynamic depending on the required mixing time and length scale. For static mixers, the Reynolds number has to be suitable high to induce turbulence enhanced mixing. Often micromixers operate in the laminar flow regime due to their small characteristic ...

The model studies optimal material distribution in a hook, which is symmetric about the z plane and consists of a linear elastic material, structural steel. It is subjected to two distributed edge load cases: One at the tip of the hook and one along its lower inner curve. The geometry is ... En savoir plus
