Function Documentation

Box intersectOffset ( const Box a_inputBox,
const Box a_domainBox,
const IntVect a_offset 
)

return a_inputBox intersected with a version of a_domainBox extended indefinitely below if offset is -1 and above if offset is +1

void order2gradient ( FArrayBox a_gradFab,
const Box a_gradBox,
const FArrayBox a_dataFab,
const Box a_dataBox,
const Vector< int > &  a_interpDimsVect 
)

Returns dx * gradient of a_dataFab, using a second-order formula. Takes data in a_dataFab available on a_dataBox and returns dx * gradient in a_gradFab on a_gradBox.

Order of components within a_gradFab, with 2D vector data: difference in data[0] in direction 0; difference in data[1] in direction 0; difference in data[0] in direction 1; difference in data[1] in direction 1.

That is: dData[0]/dx[0], dData[1]/dx[0], dData[0]/dx[1], dData[1]/dx[1].

void order2gradient ( LevelData< FArrayBox > &  a_gradData,
const LevelData< FArrayBox > &  a_data,
Vector< int >  a_interpDimsVect 
)

returns a_gradData = gradient(a_data) on wherever a_data is defined minus 1 layer

int faceDimension ( const Box a_box)

returns the dimension of the faces of a_box; crashes if not on faces of codimension 1

Box faceSlice ( const Box a_gridBox,
int  a_idir,
Side::LoHiSide  a_side,
const Box a_blockBox 
)

returns the faces of a_gridBox that are on the (a_idir, a_side) face of a_blockBox

RealVect centeringOffset ( const Box a_box,
const RealVect a_dxVect 
)

component d of return value is a_dxVect[d]/2 if a_box is cell-centered in dimension d, and 0 if node-centered in dimension d. For a d-face-centered box, returns 0 in dimension d, and a_dxVect/2 in other dimensions.

Vector<Real> VectorRealVectToReal ( const Vector< RealVect > &  a_rv)
