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. 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.

Member Function Documentation

CoarseBox() [1/2]

Box amrex::MFCellConsLinInterp::CoarseBox ( Box const &  fine, int  ratio  )

overridevirtual

Returns coarsened box given fine box and refinement ratio. This is a pure virtual function and hence MUST be implemented by derived classes.

Parameters

fine
ratio

Implements amrex::InterpBase.

CoarseBox() [2/2]

Box amrex::MFCellConsLinInterp::CoarseBox ( Box const &  fine, IntVect const &  ratio  )

overridevirtual

Returns coarsened box given fine box and refinement ratio. This is a pure virtual function and hence MUST be implemented by derived classes.

Parameters

fine
ratio

Implements amrex::InterpBase.
