T-Ω formulation with higher order hierarchical basis functions for non simply connected conductors
2016
2016 IEEE Conference on Electromagnetic Field Computation (CEFC)
This paper presents in detail the extension of the -Ω formulation for eddy currents based on higher-order hierarchical basis functions so that it can automatically deal with conductors of arbitrary topology. To this aim, we supplement the classical hierarchical basis functions with nonlocal basis functions spanning the first de Rham cohomology group of the insulating region. Such nonlocal basis functions may be efficiently and automatically found in negligible time with the recently introduced
