Function Documentation

void domainSplit ( const ProblemDomain a_domain,
Vector< Box > &  a_vbox,
int  a_maxSize,
int  a_blockfactor = 1,
IntVect  a_refineDirs = IntVect::Unit 
)

Splits domain into vector of disjoint boxes with max size maxsize.

Blocking factor is default to one. If you make minimum size > 1, then domain must be coarsenable and refineable by blockfactor (refine(coarsen(domain,blockfactor), minsize) == domain) or an error is thrown. This would be defined in MeshRefine.H, except that it needs to use a BRMeshRefine object. Here a_refineDirs[d] is 1 if refining in dimension d, and 0 if not.

void domainSplit ( const Box a_domain,
Vector< Box > &  a_vbox,
int  a_maxSize,
int  a_blockfactor = 1,
IntVect  a_refineDirs = IntVect::Unit 
)

Splits domain into a vector of disjoint boxes with maximum size maxsize. blocking factor is default to one. If you make minimum size > 1, then domain must be coarsenable and refineable by blockfactor (refine(coarsen(domain,blockfactor), minsize) == domain) or an error is thrown. This would be defined in MeshRefine.H, except that it needs to use a BRMeshRefine object. Here a_refineDirs[d] is 1 if refining in dimension d, and 0 if not.

void breakBoxes ( Vector< Box > &  a_vboxin,
const int &  a_maxSize,
const int &  a_idir 
)

Recursive function to enforce max size of boxes in a given direction. Does not call Meshrefine.
