When analyzing rotors, it is common that bearings are modeled through their effective dynamic coefficients about a static equilibrium position. This model illustrates how to compute such coefficients for a cylindrical journal bearing. The bearing length is kept much smaller than its ... En savoir plus
A surface acoustic wave (SAW) is an acoustic wave propagating along the surface of a solid material. Its amplitude decays rapidly, often exponentially, through the depth of the material. SAWs are utilized in many kinds of electronic components, including filters, oscillators, and ... En savoir plus
The majority of 3D CAD files include only the geometry of the product to be manufactured. For finite element analysis, however, you find yourself often in a situation where additional geometry is needed, for example, to analyze the flow inside or outside a device. This tutorial, ... En savoir plus
An axisymmetric 3D structure such as a conical horn antenna can be simulated in a fast and efficient way using only its 2D layout. In this model, the antenna radiation and matching characteristics are computed very quickly with respect to the dominant TE mode from the given circular ... En savoir plus
This model exemplifies how to compute the internal temperature distribution in a prismatic battery during a high-rate charge. The electrochemistry is described by a a lumped two-electrode model, which is coupled to the heat transfer model. The heat transfer model includes the effects of ... En savoir plus
Steel structures immersed in seawater can be protected from corrosion through cathodic protection. This protection can be achieved by an impressed external current or by using sacrificial anodes. The use of sacrificial anodes is often preferred due to its simplicity. This example models ... En savoir plus
Applying an electric field across a suspension of immiscible liquids may stimulate droplets of the same phase to coalesce. The method known as electrocoalescence has important applications, for instance, in the separation of oil from water. To model electrocoalescence, you need to solve ... En savoir plus
This example demonstrates the wrinkling phenomenon in a thin sheet stretched uniaxially. The modified membrane theory, which incorporates the wrinkling model, ensures noncompressive principal stresses in the wrinkled region. The analytical results are compared to the numerical results.

This tutorial example shows how to perform a random vibration analysis of a structure using power spectral density (PSD). The computations are based on the modal reduced order model (ROM). En savoir plus
This example simulates electroplating of a printed circuit board (PCB) in 3D using the Secondary Current Distribution interface. In order to achieve thickness uniformity across the PCB, a dummy pattern is included in the design, along with an aperture in the electroplating bath. En savoir plus
