Detailed Description

Class which can interpolate ghost cells across the coarse-fine interface. To select an interpolation method, use the type argument.

This class works by computing slopes on the coarse grid. We then interpolate within the coarse-grid cell to the fine-grid ghost cell, using the computed slopes. Note that all fine-grid ghost cells are interpolated from the coarse grid. Thus, this interpolator is useless for multigrid.

Member Data Documentation

◆ m_coarsenedFineGhosts

LayoutData<BaseIVFAB<VolIndex> > EBGhostCellInterpolator::m_coarsenedFineGhosts

protected

List of coarse-grid cells that appear through coarsening a fine-grid ghost cell.

This is used to accelerate interpolation fine-grid cut-cells that are also ghost cells. Doing this to avoid in-place coarsening of the fine grid ghost cell.

◆ m_ghostCF

int EBGhostCellInterpolator::m_ghostCF

protected

Number of ghost cells to fill across coarse-fine interface.

Note: Only applies the the cut-cells.
