Detailed Description

Class StaggeredStokesPETScVecUtilities provides utility functions for PETSc Vec objects.

Member Function Documentation

constructDataSynchSchedule()

Pointer< RefineSchedule< NDIM > > IBAMR::StaggeredStokesPETScVecUtilities::constructDataSynchSchedule ( int  u_data_idx, int  p_data_idx, SAMRAI::tbox::Pointer< SAMRAI::hier::PatchLevel< NDIM > >  patch_level  )

static

Construct a RefineSchedule to synchronize shared values that can be used in conjunction with copyFromPatchLevelVec().

Note

Synchronization is not required for all data centerings. For cases in which it is not needed, this method will return a NULL pointer.

constructPatchLevelAO()

void IBAMR::StaggeredStokesPETScVecUtilities::constructPatchLevelAO ( AO &  ao, std::vector< int > &  num_dofs_per_proc, int  u_dof_index_idx, int  p_dof_index_idx, SAMRAI::tbox::Pointer< SAMRAI::hier::PatchLevel< NDIM > >  patch_level, int &  u_ao_offset, int &  p_ao_offset  )

static

Create an application ordering object (AO) that creates a mapping between global PETSc indices and mapping of SAMRAI data indices for patch data index dof_index_idx to a nonnegative integer on a SAMRAI::hier::PatchLevel.

See also

IndexUtilities::mapIndexToInteger() for details on the integer mapping of SAMRAI data indices.

Parameters

ao_offset

An integer offset used for integer mapping of SAMRAI data indices.

constructPatchLevelDOFIndices()

void IBAMR::StaggeredStokesPETScVecUtilities::constructPatchLevelDOFIndices ( std::vector< int > &  num_dofs_per_proc, int  u_dof_index_idx, int  p_dof_index_idx, SAMRAI::tbox::Pointer< SAMRAI::hier::PatchLevel< NDIM > >  patch_level  )

static

Assign a DOF index to each unique degree of freedom on a SAMRAI::hier::PatchLevel.

The DOF indices generated by this method are compatible with the parallel PETSc Vec objects generated by constructPatchLevelVec().

Note

DOF indices are not assigned to ghost cell values by this method.
