This example benchmarks a NAFEMS validation model of a friction contact problem with an elastoplastic material model. A thin metal sheet is forced into a die by a punch. Both the compressing displacement and the release of the punch are modeled in order to compute the forming angle (at ... En savoir plus
Piezoelectric valves are frequently employed in medical and laboratory applications due to their fast response times and quiet operation. Their energy efficient operation, also dissipates little heat, which is often important for these applications. This model shows how to model a ... En savoir plus
In an alkaline electrolyzer stack, all cells share the same electrolyte. As a result of all cells being in ionic contact, parasitic shunt currents flow between the cells through the manifolds and the electrolyte channels, on both the inlet and outlet side. This example models a ... En savoir plus
This example simulates the insertion of a snap hook in its groove. Fasteners like this are common in the automotive industry, for example, in the control panel of a car. In this case it is important to know the force that must be applied in order to place the hook in the slot and also ... En savoir plus
An Evans droplet experiment is a century-old corrosion experiment for demonstrating oxygen transport-limited corrosion. A droplet of water is placed on a metal surface, and over time the surface features differences in the radial direction of the surface in terms of amount of corroded ... En savoir plus
When radiation occurs across a very narrow gap this is often well-approximated as radiation between infinite parallel plates. This model considers three aluminum plates separated by narrow air gaps. The model compares the classical approach, based on the Surface-to-Surface Radiation ... En savoir plus
Acoustic droplet ejection is a non-contact, highly controllable method for liquid handling emerging in applications such as printing, biomedical, semiconductor assembly, and mass spectroscopy. The modeling approach assumes separation of acoustic and flow time scales. First, a focused ... En savoir plus
This model simulates atmospheric galvanic corrosion of a busbar, which includes a copper flange, an aluminum alloy flange in contact with a zinc nut and bolt. The Secondary Current Distribution interface is used to solve for the electric potential in electrode domain and Current ... En savoir plus
In this application, a solution is pumped through a catalytic bed where a solute species reacts as it gets in contact with the catalyst. The purpose of this example is to maximize the total reaction rate for a given total pressure difference across the bed by finding an optimal catalyst ... En savoir plus
The miniaturization of electronics devices requires batteries with higher energy density and power. To increase the contact area between the electrodes and the solid electrolyte, 3D configurations such as the trench geometry are used. This example demonstrates how to model a solid-state ...
