Detailed Description

Linear conservative interpolation on cell centered data.

Linear conservative interpolation on cell centered data I.e, conservative interpolation with a limiting scheme that preserves the value of any linear combination of the fab components; //!< e.g.,

if sum_ivar a(ic,jc,ivar)*fab(ic,jc,ivar) = 0, then sum_ivar a(ic,jc,ivar)*fab(if,jf,ivar) = 0 is satisfied in all fine cells if,jf covering coarse cell ic,jc.
