2D AND 3D EIKONAL SOLVERS



FDTIMES package is written by Pascal Podvin  (MINES ParisTech / Centre de Géosciences/Géophysique)

  • This package includes the functions time_2d() and time_3d() devoted to computation of first arrival times on cartesian grids by finite-differences.
  • The routines are delivered with a few simple examples in Fortran and C demonstrating their usage.
