Function Documentation

◆ getLHCBoxes()

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).

◆ eblohicenter()

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.

◆ eblohicenterFace()

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.
