This function is used when in direction a_dir a 3 point stencil of cell- centered data is being used to compute something at the cell center of the center cell of the stencil. The data for the stencil is valid in a_inBox. It divides a_inBox into a cell-centered box where the full stencil can be used, a_centerBox, and cell-centered boxes where 2 point stencils can be used, a_loBox and a_hiBox based on the current problem domain, a_domain, and the stencil direction, a_dir. The union of these 2 and 3 point stencel boxes is returned as a_entireBox. The 2 point stencil boxes are one wide, at most, and if they have been defined then the corresponding flag, a_hasLo or a_hasHi, is set to one, otherwise these flags are zero. All output boxes lie within the domain. |

This function is used when in direction a_dir a 2 point stencil of cell- centered data is being used to compute something at the cell face between the cell centers of the stencil. The data for the stencil is valid in a_inBox. It uses a_inBox to compute a box (face-centered in a_dir) where the full stencil can be used, a_centerBox, and boxes (face-centered in a_dir) where a 1 point stencil can be used, a_loBox and a_hiBox based on the current problem domain, a_domain, and the stencil direction, a_dir. The union of these 1 and 2 point stencel boxes is returned as a_entireBox (face-centered in a_dir). The 1 point stencil boxes are one wide, at most, and if they have been defined then the corresponding flag, a_hasLo or a_hasHi, is set to one, otherwise these flags are zero. All output boxes lie within the domain. |
