Initial data

The routine initialdata is required in all user defined applications. Initial data are defined in this routine.

subroutine initialdata(u0, u2, v, w, par)
                  type(gridfunction), dimension(NU) :: u0,u2
                  type(gridfunction), dimension(NV) :: v
                  type(gridfunction), dimension(NW) :: w
                  CCTK_REAL, dimension(:) :: par
The ufuncs and vfuncs should be defined using the pointers "u0" and "v", respectively.
Pointer "u2" is for scratch space. It has the same memory layout as "u0" and can be used to faciliate setting up initial data. However, data written to memory pointed to by "u2" will be overwritten after routine initialdata is finished. Use pointer "u0" for finalizing initial data, not "u2".
