VectorTransformation CubedSphere2DCS::vectorBlockTransformation ( int  a_nDst,

virtual

return vector transformation from one block to another at a point.

Return object that transforms the components of a vector situated at a_xiSrc from basis of block a_nSrc to components in basis in block a_nDst.

Default implementation goes through real space.

Reimplemented from MultiBlockCoordSys.

void CubedSphere2DCS::cartesianFromMapped ( Real xx,
Real yy,
Real zz,
const RealVect a_xiSrc,
int  a_nSrc 
) const

convert from mapped coordinate to Cartesian coordinates

given a_xiSrc in block a_nSrc, return 3D Cartesian coordinates of point.

void CubedSphere2DCS::mappedFromCartesian ( RealVect a_xiDst,
int  a_nDst,
Real  xx,
Real  yy,
Real  zz 
) const

convert from Cartesian coordinates to mapped coordinate

given 3D Cartesian coordinates of point and destination block returns mapped coordinates of that point. Radius information is discarded.

virtual void CubedSphere2DCS::blockRemapping ( RealVect a_xi_valid,
int &  a_n_valid,
const RealVect a_xiSrc,
int  a_nSrc 
) const
virtual

block mapping conversion function

given a_xiSrc in block a_nSrc, returns which block (a_n_valid) contains that location in its valid region and its location (a_xi_valid) in that block's computational coordinate space.

Implements MultiBlockCoordSys.

virtual RealVect CubedSphere2DCS::blockRemappingGeneral ( int  a_nDst,
const RealVect a_xiSrc,
int  a_nSrc 
) const
virtual

given mapped coordinate a_xiSrc of a point in block a_nSrc return mapped coordinates in block a_nDst.

Reimplemented from MultiBlockCoordSys.

const Vector< int > &  a_dstBlocks,
const RealVect a_srcCoords,

virtual

return displacements

Return a Vector of same length as a_dstCoords and a_dstBlocks, with component i of this Vector being the displacement from point a_srcCoords in mapped coordinates of block a_srcBlock to point a_dstCoords[i] in mapped coordinates of block a_dstBlocks[i].

If this method is not overwritten, then component i of the returned Vector is simply the displacement in physical coordinates from a_srcCoords to a_dstCoords[i].

Reimplemented from MultiBlockCoordSys.

Have separate volume flux on each block. Normally does nothing, but cubed-sphere coordinate system needs it.
