The finite-element time-domain (FETD) method based on the use of hanging variables to generate nested grids is used as an interface between the coarse and fine grids in the FDTD subgridding method. Since the formulation for treating hanging variables is based on a Galerkin-type intergrid boundary operator, the resulting FDTD subgridding algorithm is guaranteed to be stable. Numerical examples such...
Treatment of hanging variables for nested rectangular and hexahedral elements is formulated. The Galerkin-type treatment that involves the construction of intergrid boundary operator leads to symmetric mass and stiffness matrices, otimes-method is used for the temporal discretization in the finite element time domain method. The conditions for numerical stability of both implicit and explicit FETD...
