const FaceIndex &    a_thisFace,
const EBISBox &    a_ebisBox,
const Box &    a_domain,
const int &    a_dir
)  [static]

const FaceIndex &    a_thisFace,
const EBISBox &    a_ebisBox,
const Box &    a_domain,

)  [static]
 

return the dotproduct of two ebfabs, Only uncovered regions count here.

const BoxLayout &    a_layout,
const EBISLayout &    a_ebisl,
const int &    a_comp
)  [static]
 

return the dotproduct of two leveldatas of ebfabs, Only uncovered regions count here.

bool EBArith::getAdjacentFace (  FaceIndex &    a_adjacentFace,
const FaceIndex &    a_face,
const EBISBox &    a_ebisBox,
const Box &    a_domain,
const int &    a_idir,
const Side::LoHiSide &    a_side
)  [static]
 

Return true if there is a unique adjacent face in the given direction. False if either covered or multivalued.

const IntVect &    a_timesMoved,
const IntVect &    a_pathSign,

const VolIndex &    a_vof1,
const IntVect &    a_cell2,
const EBISBox &    a_ebisBox
)  [static]
 

Given a VoF, a_vof1, and a cell, a_cell2, determine if there is a single VoF in a_cell2 that connects to a_vof1 via a monotone path. If there is one such VoF then TRUE is returned (and the VolIndex is returned, a_vof2). If there is no such VoF or if there are more than one such VoF then FALSE is returned (and a_vof2 is unchanged).

return l-p norm of a_src. if p==0, v norm returned is Max(abs(a_src)) over uncovered regions. otherwise, returns 1/vol(sum(volfrac*a_src(iv,comp)**p)^(1/p)) of component comp of a_src weighted by local volume fraction and also returns volume of uncovered regions. Only uncovered regions count here. The data must have the same layout as a_layout with the possible exception of ghost cells.

return lp-norm of component comp of a_src, weighted by local volume fraction. not normalized by number of points or anything like that. if p==0, volume returned is one and norm returned is Max(abs(a_src)) over uncovered regions. otherwise, returns sum(volfrac*a_src(iv,comp)**p) of component comp of a_src weighted by local volume fraction and also returns volume of uncovered regions.
