List of all members.

Detailed Description

EBIndexSpace represents the geometric information of the domain. It should be generated through the Chombo_EBIS class. This follows the singleton pattern.

Construction of the EBIndexSpace can follow one of methods 1. From a previously written out HDF5 file. This is a representation of the EBIndexSpace at the finest level. When this is read back into a running application the EBIndexSpace at the coarser levels is regenerated on construction 2. As a GeometryService. The base class for Geometry objects. 3. As a Workshop object that reads the finest level EB boxes from the EBIndexSpace itself and fills in the data structure as it accepts it. 4. As a Worshop object that has an already defined data decomposition

Member Function Documentation

void EBIndexSpace::define ( const ProblemDomain &  a_domain,
const RealVect &  a_origin,
const Real &  a_dx,
const GeometryService &  a_geoserver,
int  a_nCellMax = -1,
int  a_maxCoarsenings = -1 
)

If a_ncellMax is set, that is the max width of an internal grid. Otherwise use defaults of (16 in 3D, 64 in 2d)

This

void EBIndexSpace::define ( HDF5Handle &  a_handle,
ProblemDomain  a_finestLevel 
)

reads in all levels from finest level down

void EBIndexSpace::define ( HDF5Handle &  a_handle,
int  a_maxCoarsenings = -1 
)

defines from one level and then does coarsening

void EBIndexSpace::define ( EBISLevel *  a_level0,
int  a_nCellMax = -1,
int  a_maxCoarsenings = -1 
)

void EBIndexSpace::define ( const ProblemDomain &  a_entireDomain,
const RealVect &  a_origin,
const Real &  a_dx,

)

EBISLevel* EBIndexSpace::buildNextLevel ( const GeometryService &  a_geoserver,
int  a_nCellMax,
bool  a_fixRegularNextToMultiValued = true 
)

bool EBIndexSpace::setDistributedData (  )  [inline]

Set a flag that indicates the data defining the EB is distributed. This will signal EBISLevel to hand grid generation off to the GeometryService. Function returns previous value of m_distributedData. Call this before define() if this functionality is desired.

References m_distributedData.

int EBIndexSpace::numLevels (  )  const

long long EBIndexSpace::numVoFs ( const ProblemDomain &  a_domain  )  const

Get the number of vofs over the entire domain. This is blocking as a broadcast and gather are required.

Real EBIndexSpace::totalVolFrac ( const ProblemDomain &  a_domain  )  const

Get the total of the volume fractions over the entire domain. This is blocking as a broadcast and gather are required.

int EBIndexSpace::getLevel ( const ProblemDomain &  a_domain  )  const

return level index of domain. return -1 if a_domain does not correspond to any refinement of EBIS.

RealVect EBIndexSpace::getOrigin (  )  const [inline]

References m_ebisLevel.

const ProblemDomain& EBIndexSpace::getBox ( int  level  )  const [inline]

returns the problem domain box at a level of refinement

bool EBIndexSpace::isDefined (  )  const

Return true if the define function has been called.

void EBIndexSpace::clear (  ) 

int EBIndexSpace::getNCellMax (  )  const

void EBIndexSpace::write ( HDF5Handle &  a_handle,
ProblemDomain  a_outputLevel = ProblemDomain() 
) const

Writes out finest level as a default. Writes at the level you are domain you want if a_outputLevel is defined.

void EBIndexSpace::writeInfo ( HDF5Handle &  handle  )  const

void EBIndexSpace::writeAllLevels ( HDF5Handle &  a_handle  )  const

Outputs ALL levels of the EBIS. this is the one to use if you want to do all definition through the file (no coarsening).

void EBIndexSpace::readInAllLevels ( HDF5Handle &  a_handle,
ProblemDomain  a_finestLevel 
)

Define entirely from the input file. a_finestLevel can be a coarsening of the finest level in the file. No coarsening algorithm is done.
