This application provides insight into the instantaneous and periodic steady state solutions of a 1D capacitively coupled plasma. The geometry, pressure and applied voltage are all inputs, as is the frequency and number of RF cycles over which to solve. Aside from instantaneous and time averaged plots, global quantities for the power deposition and current are computed.
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. This model simulates a simplified model of a horizontal-axis portable washing machine and predicts the verge of ...
A diplexer is a device that combines or splits signals into two different frequency bands, widely used in mobile communication systems. This model simulates splitting properties using a simplified 2D geometry. The computed S-parameters and electric fields at the lower and upper bands will show the diplexer characteristics in the Ka-band.
This model exemplifies how the rate of steel corrosion in an oil platform increases over time due to build-up of a resistive film on the sacrificial anodes, formed by reaction products. The model also includes secondary current distribution electrode kinetics on the protected steel structure, defining simultaneous metal dissolution and oxygen reduction (mixed potential).
This example models electrocoating of paint onto a car door in a time-dependent simulation. The deposited paint is highly resistive which results in lowered local deposition rates for coated areas. A primary current distribution in combination with a film resistance model is used to describe the charge transport in the electrolyte. The model is in 3D and uses an imported CAD geometry.
In the search for weight reduction, the cross-section of an eyeglass frame is continuously reduced. The thin section over the nose transfers the entire load between the two halves. This example predicts the fatigue life using the combined Basquin and Coffin-Manson model when eyeglasses are subjected to bending.
This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in Pro/ENGINEER by using the LiveLink interface.
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 mechanism in a crane modeled in the Multibody Dynamics module is optimized using the Optimization module. The target ...
This is a busbar configuration with an AC analysis. The configuration is similar to the introductory tutorial in the book Introduction to COMSOL Multiphysics. However, two conductors are added to represent a more realistic case of magnetic fields surrounding the busbar. The results include Lorentz forces, induced currents, magnetic flux, and temperature.
This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in Creo Parametric by using the LiveLink interface.
