Removing Details in Model Geometries

This model illustrates how to use the *Remove Details* operation to automatically find and remove small details from a model geometry. Per saperne di più

Optimization of a Crane Link Mechanism

In complex mechanical systems, it can be challenging to find an optimal (or even good enough) solution only through engineering insight or trial-and-error procedures. Using mathematical optimization methods can then be an efficient path to a better design. In this example, a link ... Per saperne di più

A broad range of American and European ... Per saperne di più

Ply Drop-Off in a Composite Panel

Ply drop-off often occurs in composite laminates to tailor the laminate thickness based on the loading requirements. This example illustrates the modeling of ply drop-off in a composite panel. The panel considered for the analysis has symmetric angle-ply layup with three sections: thick, ... Per saperne di più

Mechanics of a Golf Swing

How well you can strike a golf ball is not only determined by your muscle strength, but more importantly it is influenced by the mechanics of golf swing. The outcome of golf stroke is basically determined by the movement of the club head just prior to the impact with the ball. In this ... Per saperne di più

Caughey-Thomas Mobility

With an increase in the parallel component of the applied field, carriers can gain energies above the ambient thermal energy and be able to transfer energy gained by the field to the lattice by optical phonon emission. The latter effect leads to a saturation of the carriers mobility. The ... Per saperne di più

Modeling Current Distribution in a 3D Lead-Acid Battery Grid Battery

This 3D model example demonstrates the use of the Lead-Acid Battery interface for modeling current distribution in full cell employing a lead-acid battery chemistry. The lead acid battery chemistry uses PbO2 as the positive porous electrode and Pb as the negative porous electrode and ... Per saperne di più

Electrodeposition on a Resistive Patterned Wafer

This example models time-dependent copper deposition on a resistive wafer in a cupplater reactor. As the deposited layer builds up, the resistive losses of the deposited layer decreases. The benefit of using a current thief for a more uniform deposit is demonstrated. Per saperne di più

Walking Instability in a Washing Machine

Walking instability, due to non-uniform distribution of clothes, is a common problem in lightweight portable washing machines. This problem is more severe in horizontal-axis washing machines, which are more popular because of their high efficiency in spite of high manufacturing cost. ... Per saperne di più

Critical Speed of a Dual Rotor System

Due to the demand for larger power with a smaller size, dual-shaft systems with intershaft bearings are becoming a standard configuration for gas turbine engines. Such systems consist of two coaxial rotors running at different speeds, interlinked through a multi-spool bearing. In this ... Per saperne di più
