Function Documentation

void getLHCBoxes ( Box a_loBox,
Box a_hiBox,
Box a_centerBox,
int &  a_haslo,
int &  a_hashi,
const Box a_inBox,
const ProblemDomain a_dProblem,
const int &  a_dir 
)

divide a box into its centered-diff boxes, its one-sided boxes and tell whether the one sided boxes are there. The one-sided boxes are one wide at most. All Boxes are intersected with the domain. InBox should be the size of the domain of computation (the size of the gradient box).

void eblohicenter ( Box a_loBox,
int &  a_hasLo,
Box a_hiBox,
int &  a_hasHi,
Box a_centerBox,
Box a_entireBox,
const Box a_inBox,
const ProblemDomain a_domain,
const int &  a_dir 
)

Divide a box, a_inBox, into a box where centered differences can be used, a_centerBox, and boxes where one-sided difference can be used, a_loBox and a_hiBox based on the current problem domain, a_domain, and the difference direction, a_dir. The union of these computation boxes are returned as a_entireBox. The one-sided difference 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 it is zero. All boxes lie within the domain, a_domain.

void eblohicenterFace ( Box a_loBox,
int &  a_hasLo,
Box a_hiBox,
int &  a_hasHi,
Box a_centerBox,
Box a_entireBox,
const Box a_inBox,
const ProblemDomain a_domain,
const int &  a_dir 
)

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.
