A new mesh generation method suitable for analyzing asymmetric coaxial cables

摘要

We propose a new mesh generation method suitable for analyzing asymmetric (off-centered inner conductor) coaxial cables by FEM. Our method is characterized by the use of complex holomorphic mapping that transform the original region to a true annulus region. As is well known, the desirable division for given problems on a true annulus region may be easily performed. And, we transform the obtained mesh on a true annulus region to the original region where the problem is set to get final results. We also show one example based on our new mesh generation method.
