If you want to see 3D field distributions, you will have to use a
program based on a time domain method such as finite-difference time
domain (FDTD) or transmission-line matrix (TLM) methods. These are
available from universities such as University of Illinois or
Pensilvania State University, but complicated to use, and will take from
many hours to several days (depending on the line length) on PC with at
least 64 Megs of memory for a single line. In addition, conventional
FDTD is not even able to handle conductor loss with any practical
