The file Radial Comb.ach is provided in the Tutorials\Models subdirectory of the ALGOR installation directory.
Materials:
The comb parts are made of polysilicon with a dielectric constant of 10,000.
The air has a dielectric constant of 1.
A voltage difference of 10V will be applied to the radial comb motor as shown below.
Calculate the Coulomb forces that are generated so that they can be applied in a static stress analysis.
