NAME

  Grid_computeVarDiff

SYNOPSIS

  call Grid_computeVarDiff(integer(in) :: level,
                integer(in) :: gr_iRefSoln,
                integer(in) :: gr_iSoln,
                integer(in) :: ires)

DESCRIPTION

  Compute the current difference of two variables.
  Only the leaf block residuals are calculated.

ARGUMENTS

  level        - the level (of leaf blocks) to take the residual for, or -1 
                 for all LEAF blocks.
  gr_iRefSoln  - the "reference solution" variable
  gr_iSoln     - "the solution" variable
  ires         - the residual variable

RESULT

  The difference between the reference solution and solution in the blocks
  (either selected by level, or all LEAF blocks)
  is placed in the variable ires.
