New version of FDTD with GFM program in Schwarzschild space-time

Finite difference time domain (FDTD) method in curved space–time is developed by filling the flat space–time with an equivalent medium. Green function Method (GFM) in curved space–time is solving transport equations. This is a new version of FDTD and GFM program in Schwarzschild space–time. The code for connection boundary and output boundary are included into the new version, so that electromagnetic scattering problem (not by black holes) in Schwarzschild space–time can be solved by this new version.
