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 ... Mehr lesen
In this model, we introduce a cloaking method using an electrically tuned monolayer of graphene. We will show that when a cylindrical dielectric scatterer is covered in graphene, the scattering cross section is greatly reduced at the designated frequency, making it electromagnetically ...

This tutorial utilizes the Particle Beam feature to examine the performance of a high-precision spectrometer. An ion beam is subjected to electric and magnetic forces, and only a fraction of the incoming beam is transmitted to the detector. The Particle Counter feature is used to compute ... Mehr lesen
The electron energy distribution function (EEDF) plays an important role in the overall behavior of discharges. In this example, the formation period of an Argon plasma is studied with special attention paid to the EEDF. The plasma is created within a 4 cm gap by a DC source voltage of 1 ... Mehr lesen
In this tutorial model, it is demonstrated how to incorporate a localized nonlinearity in a submodel. In this case, an initial elastic analysis reveals that a small region of a structure has stresses above the yield limit. To improve the results, an elastoplastic material model is added ...

This model demonstrates 3D topology and shape optimization for an extruded geometry. This can be achieved using equation-based modeling and extrusion operators. The model considers stiffness maximization of a beam subject to a constraint on the mass, but the method can be used with any ... Mehr lesen
The triaxial test is one of the most common tests used in laboratory soil testing. The soil sample is normally placed inside a rubber membrane and then compressed maintaining a radial pressure. In this model, a vertical displacement and a confinement pressure are applied on the sample ... Mehr lesen
Rotating cylinder Hull cells are an important experimental tool in electroplating and electrodeposition and are used for the measurement of nonuniform current distribution, mass transport, and throwing power of plating baths. The model reproduces the results for a commercially available ... Mehr lesen
This model shows how to use the features of the Heat Transfer Module to reduce the computation time and memory usage in view factor computations. Illustrative results of speedup and memory usage reduction are given on a benchmark model. The solution is not computed, only the view ... Mehr lesen
A 3D silicon waveguide is set up with rib and slot configurations. The meshing includes physics-controlled mesh, with the number of longitudinal mesh elements set to 50 to visualize the wave oscillation. The detailed discussion of the model setup is discussed in the blog post: "Silicon ... Mehr lesen
