2nd International Workshop on Time Domain Modelling of Fields and Networks, Berlin, October 28-29 1993.
The implications for accuracy, resolution and computational demands of a range of meshing techniques used in the transmission-line modelling (TLM) method are described. Particular emphasis is placed on the effectiveness and accuracy of the multigrid technique. It is shown that it can be simply implemented and that it offers better spatial resolution and similar accuracy at low frequencies to other method at a fraction of computational effort.
