intfilΒΆ

Signature:
subroutine intfil(val, mi, mj, time, flaguse, nrowst, ncolst, ilo, ihi, jlo, jhi, level, nvar, naux)
Arguments:
integer, intent(in):
  • mi: Horizontal dimension of the input region.
  • mj: Vertical dimension of the input region.
  • nrowst: Starting i-index of the patch, in indices relative to val.
  • ncolst: Starting j-index of the patch, in indices relative to val.
  • ilo: Lower horizontal index of the patch to fill, in global indices.
  • ihi: Upper horizontal index of the patch to fill, in global indices.
  • jlo: Lower vertical index of the patch to fill, in global indices.
  • jhi: Upper vertical index of the patch to fill, in global indices.
  • level: Level of the input region.
  • nvar: Number of solution variables.
  • naux: Number of aux variables.
double precision, intent(inout):
  • val: Array of solution values on the patch being filled.
double precision, intent(out):
  • flaguse(ilo:ihi,jlo:jhi): Indicates where the patch is successfully filled. flaguse is initialized to 0.d0, and set to 1.d0 in every location of the patch that gets filled. It is also set to 1.d0 in all cells outside the computational domain, as these will be filled in later using boundary data.
double precision, intent(in):
  • time: Time on the patch being filled.
Description:

Attempts to fill a rectangular patch of val and aux, which contain solution and aux values on an input region. Values are needed at time time, and at level level.

This routine only copies information from grids at level level into the patch; no spatial interpolation is done here.

In indices relative to val and aux, the lower-left corner of the patch is at (nrowst,ncolst). In global indices, its lower-left corner is at (ilo,jlo), and its upper-right corner is at (ihi,jhi).

This is a subprocess of filrecur.
