Abstract

Based on curl-conforming basis functions and divergence-conforming basis functions for E and B fields, a new non-interative implicit time stepping scheme is proposed to efficiently solve sequentially ordered systems. The new scheme features a reordering of the linear system and a block LDU (lower-diagonal-upper) decomposition, thereby reducing the computational complexity of the original system.
