Micropumps are key components of microfluidic systems with applications ranging from biological fluid handling to microelectronic cooling. This model simulates the mechanism of a valveless micropump, that is designed to be effective at low Reynolds numbers, overcoming hydrodynamic ... En savoir plus
This Application Gallery entry demonstrates how Far-Field radiation can be calculated when a substrate is present. Two approaches are demonstrated. A simplified form that works for two homogeneous domains, and a general approach that can handle multiple, inhomogeneous layers. This ... En savoir plus
Squeeze film dampers are components that provide additional damping to rotating machines. To simplify the modeling of a rotor assembly, squeeze film dampers are modeled in terms of their damping coefficients which are a functions of the journal location in the damper. This model computes ... En savoir plus
This example shows how to model Lithium diffusion in a silicon electrode that swells. The model shows how swelling-induced plastic deformation can increase the maximum state of charge (SOC). En savoir plus
This model presents a 2D simulation of transient arc discharge movement along guided copper rails. While accurately modeling transient arcs typically requires a 3D simulation, the 2D approach offers greater efficiency and remains valuable for initial investigations and demonstration ...

This example exemplifies how to model the switching between current and voltage excitations in Terminal boundary conditions. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Control Current and Voltage Sources with the AC/DC Module". En savoir plus
The following model examines unsteady, incompressible flow past a long cylinder placed in a channel at right angle to the oncoming fluid. The cylinder is offset somewhat from the center of the flow to make the steady-state symmetrical flow unstable. The simulation time necessary for a ... En savoir plus
This model demonstrates how to use the Interior Contact feature to model the contact pressure at a bolted joint connecting two copper busbars. The AC current flowing through the assembly is induced to flow close to the outside boundaries of the conductors, but the contact resistance is ... En savoir plus
Ion implantation is used extensively in the semiconductor industry to implant dopants into wafers. Within an ion implanter, ions generated within an ion source are accelerated by an electric field to achieve the desired implant energy. Ions of the correct charge state are selected by ...
