Member Data Documentation

d_hierarchy

SAMRAI::tbox::Pointer<SAMRAI::hier::BasePatchHierarchy<NDIM> > IBTK::SAMRAIGhostDataAccumulator::d_hierarchy

protected

Pointer to the patch hierarchy under consideration.

d_var

SAMRAI::tbox::Pointer<SAMRAI::hier::Variable<NDIM> > IBTK::SAMRAIGhostDataAccumulator::d_var

protected

Pointer to the variable whose data layout we copied.

d_gcw

const SAMRAI::hier::IntVector<NDIM> IBTK::SAMRAIGhostDataAccumulator::d_gcw

protected

Ghost cell width.

d_coarsest_ln

const int IBTK::SAMRAIGhostDataAccumulator::d_coarsest_ln = invalid_level_number

protected

Coarsest level of the patch hierarchy on which we work.

d_finest_ln

const int IBTK::SAMRAIGhostDataAccumulator::d_finest_ln = invalid_level_number

protected

Finest level of the patch hierarchy on which we work.

d_cc_data

bool IBTK::SAMRAIGhostDataAccumulator::d_cc_data = true

protected

Boolean indicating whether or not we have cell-centered data.

d_global_dof_idx

int IBTK::SAMRAIGhostDataAccumulator::d_global_dof_idx = IBTK::invalid_index

protected

Index into d_hierarchy that contains the dof numbering.

d_local_dof_idx

int IBTK::SAMRAIGhostDataAccumulator::d_local_dof_idx = IBTK::invalid_index

protected

Index into d_hierarchy that contains the local (i.e., the indices directly into the buffer owned by each Vec in d_vecs) dof numbering.

d_vecs

std::vector<Vec> IBTK::SAMRAIGhostDataAccumulator::d_vecs

protected

PETSc Vec objects storing the global ordering on each level.
