This is an example of optimal control, where the input heating power to a rod is optimized to give a certain temperature on the outside of the rod. This is where the maximum water temperature occurs, while the minimum occurs at the center. Therefore this problem corresponds to the ... 詳細を見る
This example simulates an oil droplet rising through a suspension. The suspension is initially stratified, with a dense layer between two clear layers. The droplet is initially located in the bottom clear layer. The particles in the suspension start to sediment toward the bottom of the ... 詳細を見る
This model simulates the propagation of a positive streamer in a weak electric field where the process of photoionization is essential to provide seed electrons at the front of the streamer head. The simulated electric field and electron density as a function of time agree well with that ... 詳細を見る
Using a Fluid-Solid Interaction multiphysics interface, the behavior of a spring-loaded ball check valve is studied under varying functional and reverse flow. The fluid force acting on the ball opens the valve at the opening pressure. In the case of a reversed pressure, the ball comes ... 詳細を見る
Die forming is a widespread sheet metal forming manufacturing process. The workpiece, usually a metal sheet, is permanently reshaped around a die through plastic deformation by forming and drawing processes. Simulations can be carried out in order to avoid cracks, tears, wrinkles, too ... 詳細を見る
The following example solves a pure conduction and a free-convection problem in which a vacuum flask holding hot coffee dissipates thermal energy. The main interest is to calculate the flask's cooling power; that is, how much heat it loses per unit time. This tutorial model treats the ... 詳細を見る
Diaphragm accumulators are essential components that store energy and regulate hydraulic systems. A flexible rubber diaphragm divides the hydraulic fluid from a compressible inert gas, typically nitrogen. These accumulators perform multiple tasks, such as temporarily storing hydraulic ... 詳細を見る
This model simulates a negative dielectric barrier discharge under a point-to-plate electrode configuration. Two solid dielectric layers are inserted into the air gap. A negative voltage of 2.5 kV is applied to the cathode electrode, initiating a corona streamer that propagates and ... 詳細を見る
This example shows how to set up a piezoelectric transducer problem following the work of Y. Kagawa and T. Yamabuchi. The composite piezoelectric ultrasonic transducer has a cylindrical geometry that consists of a piezoceramic layer, two aluminum layers, and two adhesive layers. The ... 詳細を見る
The GEC cell was introduced by NIST in order to provide a standardized platform for experimental and modeling studies of discharges in different laboratories. The plasma is sustained via inductive heating. The Reference Cell operates as an inductively-coupled plasma in this model. This ... 詳細を見る
