| virtual void | block_setup () |
| Determine the size of the matrix blocks and setup the lookup schemes relating the global degrees of freedom with their "blocks" and their indices (row/column numbers) in those blocks. The distributions of the preconditioner and the internal blocks are automatically specified (and assumed to be uniform) at this stage. This method should be used if the identity dof-to-block mapping is okay, i.e. dof number 0 corresponds to block number 0 dof number 1 corresponds to block number 1 dof number 2 corresponds to block number 2 etc...

The distributions of the preconditioner and the blocks are automatically specified (and assumed to be uniform) at this stage. This method should be used if anything other than the identity dof-to-block mapping is required. The argument vector dof_to_block_map should be of length ndof. The indices represents the dof types whilst the value represents the block types. In general we want: More... | |

| MATRIX | get_block (const unsigned &i, const unsigned &j, const bool &ignore_replacement_block=false) const |
| Return block (i,j). If the optional argument ignore_replacement_block is true, then any blocks in Replacement_dof_block_pt will be ignored throughout the preconditioning hierarchy. More... | |

| void | get_blocks (DenseMatrix< bool > &required_blocks, DenseMatrix< MATRIX * > &block_matrix_pt) const |
| Get all the block matrices required by the block preconditioner. Takes a pointer to a matrix of bools that indicate if a specified sub-block is required for the preconditioning operation. Computes the required block matrices, and stores pointers to them in the matrix block_matrix_pt. If an entry in block_matrix_pt is equal to NULL on return, that sub-block has not been requested and is therefore not available. More... | |
| void | get_dof_level_block (const unsigned &i, const unsigned &j, MATRIX &output_block, const bool &ignore_replacement_block=false) const |
| Gets dof-level block (i,j). If Replacement_dof_block_pt(i,j) is not null, then the replacement block is returned via a deep copy. More... | |
| MATRIX | get_concatenated_block (const VectorMatrix< BlockSelector > &selected_block) |
| Returns a concatenation of the block matrices specified by the argument selected_block. The VectorMatrix selected_block must be correctly sized as it is used to determine the number of sub block matrices to concatenate. More... | |
| void | get_concatenated_block_vector (const Vector< unsigned > &block_vec_number, const DoubleVector &v, DoubleVector &b) |

| void | get_block_vectors (const Vector< unsigned > &block_vec_number, const DoubleVector &v, Vector< DoubleVector > &s) const |
| Takes the naturally ordered vector and rearranges it into a vector of sub vectors corresponding to the blocks, so s[b][i] contains the i-th entry in the vector associated with block b. Note: If the preconditioner is a subsidiary preconditioner then only the sub-vectors associated with the blocks of the subsidiary preconditioner will be included. Hence the length of v is master_nrow() whereas the total length of the s vectors is the sum of the lengths of the individual block vectors defined in block_vec_number. More... | |

| Takes the naturally ordered vector and rearranges it into a vector of sub vectors corresponding to the blocks, so s[b][i] contains the i-th entry in the vector associated with block b. Note: If the preconditioner is a subsidiary preconditioner then only the sub-vectors associated with the blocks of the subsidiary preconditioner will be included. Hence the length of v is master_nrow() whereas the total length of the s vectors is Nrow.

| void | return_block_vectors (const Vector< unsigned > &block_vec_number, const Vector< DoubleVector > &s, DoubleVector &v) const |
| Takes the vector of block vectors, s, and copies its entries into the naturally ordered vector, v. If this is a subsidiary block preconditioner only those entries in v that are associated with its blocks are affected. The block_vec_number indicates which block the vectors in s came from. The block number corresponds to the block numbers in this preconditioner. More... | |
| void | return_block_vectors (const Vector< DoubleVector > &s, DoubleVector &v) const |
| Takes the vector of block vectors, s, and copies its entries into the naturally ordered vector, v. If this is a subsidiary block preconditioner only those entries in v that are associated with its blocks are affected. The block_vec_number indicates which block the vectors in s came from. The block number corresponds to the block numbers in this preconditioner. This is simply a wrapper around the other return_block_vectors(...) function where the block_vec_number Vector is the identity, i.e. block_vec_number is [0, 1, ..., nblock_types - 1]. More... | |
| void | get_block_vector (const unsigned &n, const DoubleVector &v, DoubleVector &b) const |

| void | return_block_vector (const unsigned &n, const DoubleVector &b, DoubleVector &v) const |
| Takes the n-th block ordered vector, b, and copies its entries to the appropriate entries in the naturally ordered vector, v. Here n is the block number in the current block preconditioner.

| void | get_block_ordered_preconditioner_vector (const DoubleVector &v, DoubleVector &w) |
| Given the naturally ordered vector, v, return the vector rearranged in block order in w. This function calls get_concatenated_block_vector(...) with the identity block mapping. More... | |
| void | return_block_ordered_preconditioner_vector (const DoubleVector &w, DoubleVector &v) const |
| Takes the block ordered vector, w, and reorders it in natural order. Reordered vector is returned in v. Note: If the preconditioner is a subsidiary preconditioner then only the components of the vector associated with the blocks of the subsidiary preconditioner will be included. Hence the length of v is master_nrow() whereas that of the vector w is of length this->nrow(). More... | |

| unsigned | ndof_types_in_mesh (const unsigned &i) const |
| Return the number of DOF types in mesh i. WARNING: This should only be used by the upper-most master block preconditioner. An error is thrown is this function is called from a subsidiary preconditioner. They (and since every block preconditioner can in principle be used as s subsidiary preconditioner: all block preconditioners) should store local copies of "their meshes" (if they're needed for anything) More... | |

| void | internal_get_block_ordered_preconditioner_vector (const DoubleVector &v, DoubleVector &w) const |

| void | internal_return_block_ordered_preconditioner_vector (const DoubleVector &w, DoubleVector &v) const |
| Takes the block ordered vector, w, and reorders it in the natural order. Reordered vector is returned in v. Note: If the preconditioner is a subsidiary preconditioner then only the components of the vector associated with the blocks of the subsidiary preconditioner will be included. Hence the length of v is master_nrow() whereas that of the vector w is of length this->nrow(). More... | |
| unsigned | internal_nblock_types () const |
| Return the number internal blocks. This should be the same as the number of internal dof types. Internally, the block preconditioning framework always work with the most fine grain blocks. I.e. it always deal with the most fine grain dof-level blocks. This allows for coarsening of dof types. When we extract a block, we look at the Block_to_dof_map_fine vector to find out which most fine grain dof types belongs to this block. More... | |
| unsigned | internal_ndof_types () const |
| Return the number of internal dof types. This is the number of most fine grain dof types. The preconditioner writer should not have to concern him/her-self with the internal dof/block types. Thus this fuction is moved to private. We have kept this function alive since it it still used deep within the inner workings of the block preconditioning framework. More... | |
| void | internal_return_block_vector (const unsigned &n, const DoubleVector &b, DoubleVector &v) const |
| Takes the n-th block ordered vector, b, and copies its entries to the appropriate entries in the naturally ordered vector, v. Here n is the block number in the current block preconditioner. If the preconditioner is a subsidiary block preconditioner the other entries in v that are not associated with it are left alone. More... | |
| void | internal_get_block_vector (const unsigned &n, const DoubleVector &v, DoubleVector &b) const |
| A helper function, takes the naturally ordered vector, v, and extracts the n-th block vector, b. Here n is the block number in the current preconditioner. NOTE: The ordering of the vector b is the same as the ordering of the block matrix from internal_get_block(...). More... | |
| void | internal_get_block_vectors (const Vector< unsigned > &block_vec_number, const DoubleVector &v, Vector< DoubleVector > &s) const |
| Takes the naturally ordered vector and rearranges it into a vector of sub vectors corresponding to the blocks, so s[b][i] contains the i-th entry in the vector associated with block b. The block_vec_number indicates which blocks we want. These blocks and vectors are those corresponding to the internal blocks. Note: If the preconditioner is a subsidiary preconditioner then only the sub-vectors associated with the blocks of the subsidiary preconditioner will be included. Hence the length of v is master_nrow() whereas the total length of the s vectors is the sum of the Nrow of the sub vectors. More... | |
| void | internal_get_block_vectors (const DoubleVector &v, Vector< DoubleVector > &s) const |
| A helper function, takes the naturally ordered vector and rearranges it into a vector of sub vectors corresponding to the blocks, so s[b][i] contains the i-th entry in the vector associated with block b. The block_vec_number indicates which blocks we want. These blocks and vectors are those corresponding to the internal blocks. Note: If the preconditioner is a subsidiary preconditioner then only the sub-vectors associated with the blocks of the subsidiary preconditioner will be included. Hence the length of v is master_nrow() whereas the total length of the s vectors is the sum of the Nrow of the sub vectors. This is simply a wrapper around the other internal_get_block_vectors(...) function with the identity block_vec_number vector. More... | |
| void | internal_return_block_vectors (const Vector< unsigned > &block_vec_number, const Vector< DoubleVector > &s, DoubleVector &v) const |
| A helper function, takes the vector of block vectors, s, and copies its entries into the naturally ordered vector, v. If this is a subsidiary block preconditioner only those entries in v that are associated with its blocks are affected. More... | |
| void | internal_return_block_vectors (const Vector< DoubleVector > &s, DoubleVector &v) const |
| A helper function, takes the vector of block vectors, s, and copies its entries into the naturally ordered vector, v. If this is a subsidiary block preconditioner only those entries in v that are associated with its blocks are affected. This is simple a wrapper around the other internal_return_block_vectors(...) function with the identity block_vec_number vector. More... | |
| void | internal_get_block (const unsigned &i, const unsigned &j, MATRIX &output_block) const |
| Gets block (i,j) from the matrix pointed to by Matrix_pt and returns it in output_block. This is associated with the internal blocks. Please use the other get_block(...) function. More... | |
| int | internal_block_number (const unsigned &i_dof) const |
| Return the block number corresponding to a global index i_dof. This returns the block number corresponding to the internal blocks. What this means is that this returns the most fine grain dof-block number which this global index i_dof corresponds to. Since the writer of the preconditioner does not need to care about the internal block types, this function should not be used and thus moved to private. This function should not be removed since it is still used deep within the inner workings of the block preconditioning framework. More... | |
| int | internal_index_in_block (const unsigned &i_dof) const |
| Return the index in the block corresponding to a global block number i_dof. The index returned corresponds to the internal blocks, which is the most fine grain dof blocks. More... | |

| Access function to the internal block distributions. More... | |
| void | insert_auxiliary_block_distribution (const Vector< unsigned > &block_vec_number, LinearAlgebraDistribution *dist_pt) |
| insert a Vector<unsigned> and LinearAlgebraDistribution* pair into Auxiliary_block_distribution_pt. The Auxiliary_block_distribution_pt should only contain pointers to distributions concatenated at this block level. We try to ensure this by checking if the block_vec_number vector is within the range nblock_types(). Of course, this does not guarantee correctness, but this is the least we can do. More... | |
| void | block_matrix_test (const unsigned &i, const unsigned &j, const MATRIX *block_matrix_pt) const |
| Private helper function to check that every element in the block matrix (i,j) matches the corresponding element in the original matrix. More... | |
| template<typename myType > | |
| int | get_index_of_value (const Vector< myType > &vec, const myType val, const bool sorted=false) const |
| Get the index of first occurrence of value in a vector. If the element does not exist, -1 is returned. The optional parameter indicates of the Vector is sorted or not. Complexity: if the Vector is sorted, then on average, logarithmic in the distance between first and last: Performs approximately log2(N)+2 element comparisons. Otherwise, up to linear in the distance between first and last: Compares elements until a match is found. More... | |
| void | internal_get_block (const unsigned &block_i, const unsigned &block_j, CRDoubleMatrix &output_block) const |
| Gets block (i,j) from the matrix pointed to by Matrix_pt and returns it in output_block. This is associated with the internal blocks. Please use the other get_block(...) function. More... | |
| void | get_dof_level_block (const unsigned &block_i, const unsigned &block_j, CRDoubleMatrix &output_block, const bool &ignore_replacement_block) const |

The values are local to this preconditioner, for example, even if the Doftype_in_master_preconditioner_coarse = [2,3,4], the vector Doftype_coarsen_map_coarse = [[0],[1,2]], saying your local dof types 0 should be considered as dof type 0 and dof types 1 and 2 are considered as dof type 1.

| Vector< Vector< unsigned > > | Doftype_coarsen_map_fine |
| Mapping the dof types within this preconditioner. The values in here refers to the most grain dof types. This list is automatically generated either in block_setup(...) (for the top-most preconditioner) or the turn_into_subsidiary_block_preconditioner(...) function. Please refer to the comment above Doftype_coarsen_map_coarse for more details. More... | |
| Vector< LinearAlgebraDistribution * > | Internal_block_distribution_pt |

| Vector< LinearAlgebraDistribution * > | Dof_block_distribution_pt |
| Storage for the default distribution for each dof block at this level. More... | |
| Vector< unsigned > | Allow_multiple_element_type_in_mesh |
| Vector of unsigned to indicate which meshes contain multiple element types. More... | |
| Vector< const Mesh * > | Mesh_pt |
| Vector of pointers to the meshes containing the elements used in the block preconditioner. Const pointers to prevent modification of the mesh by the preconditioner (this could be relaxed if needed). If this is a subsidiary preconditioner, then the information is looked up in the master preconditioner. More... | |
| Vector< unsigned > | Ndof_types_in_mesh |
| Storage for number of types of degree of freedom of the elements in each mesh. More... | |
| unsigned | Internal_nblock_types |
| Number of different block types in this preconditioner. Note that this information is maintained if used as a subsidiary or stand-alone block preconditioner, in the latter case it stores the number of blocks within the subsidiary preconditioner. More... | |
| unsigned | Internal_ndof_types |
| Number of different DOF types in this preconditioner. Note that this information is maintained if used as a subsidiary or stand-alone block preconditioner, in the latter case it stores the number of dofs within the subsidiary preconditioner. More... | |

Additional Inherited Members | |
| Protected Member Functions inherited from oomph::BlockPreconditioner< MATRIX > | |
| void | set_nmesh (const unsigned &n) |
| Specify the number of meshes required by this block preconditioner. Note: elements in different meshes correspond to different types of DOF. More... | |
| void | set_mesh (const unsigned &i, const Mesh *const mesh_pt, const bool &allow_multiple_element_type_in_mesh=false) |
| Set the i-th mesh for this block preconditioner. Note: The method set_nmesh(...) must be called before this method to specify the number of meshes. By default, it is assumed that each mesh only contains elements of the same type. This condition may be relaxed by setting the boolean allow_multiple_element_type_in_mesh to true, however, each mesh must only contain elements with the same number of dof types. More... | |
| void | set_replacement_dof_block (const unsigned &block_i, const unsigned &block_j, CRDoubleMatrix *replacement_dof_block_pt) |
| Set replacement dof-level blocks. Only dof-level blocks can be set. This is important due to how the dof type coarsening feature operates. More... | |
| bool | any_mesh_distributed () const |
| Check if any of the meshes are distributed. This is equivalent to problem.distributed() and is used as a replacement. More... | |
| int | internal_dof_number (const unsigned &i_dof) const |
| Return the number of the block associated with global unknown i_dof. If this preconditioner is a subsidiary block preconditioner then the block number in the subsidiary block preconditioner is returned. If a particular global DOF is not associated with this preconditioner then -1 is returned. More... | |
| unsigned | internal_index_in_dof (const unsigned &i_dof) const |
| Return the row/column number of global unknown i_dof within it's block. More... | |
| unsigned | internal_block_dimension (const unsigned &b) const |
| Return the number of degrees of freedom in block b. Note that if this preconditioner acts as a subsidiary preconditioner then b refers to the block number in the subsidiary preconditioner not the master block preconditioner. More... | |
| unsigned | internal_dof_block_dimension (const unsigned &i) const |
| Return the size of the dof "block" i, i.e. how many degrees of freedom are associated with it. Note that if this preconditioner acts as a subsidiary preconditioner, then i refers to the block number in the subsidiary preconditioner not the master block preconditioner. More... | |
| unsigned | master_nrow () const |
| Return the number of dofs (number of rows or columns) in the overall problem. The prefix "master_" is sort of redundant when used as a stand-alone block preconditioner but is required to avoid ambiguities. The latter is stored (and maintained) separately for each specific block preconditioner regardless of its role. More... | |
| unsigned | internal_master_dof_number (const unsigned &b) const |
| Takes the block number within this preconditioner and returns the corresponding block number in the master preconditioner. If this preconditioner does not have a master block preconditioner then the block number passed is returned. More... | |
| const LinearAlgebraDistribution * | internal_preconditioner_matrix_distribution_pt () const |
| access function to the internal preconditioner matrix distribution pt. preconditioner_matrix_distribution_pt always returns the concatenation of the internal block distributions. Since the writer of the preconditioner does not need to concern themselves with the internal dof/block, please use preconditioner_matrix_distribution_pt(). More... | |
| const LinearAlgebraDistribution * | preconditioner_matrix_distribution_pt () const |
| Access function to the preconditioner matrix distribution pointer. This is the concatenation of the block distributions with the identity ordering. I.e. if this preconditioner has three block types, with the three associated block distributions dist_b0, dist_b1 and dist_b2, then this distribution is: LinearAlgebraDistributionHelpers::concatenate(dist_b0, dist_b1, dist_b2).

Detailed Description
template<typename MATRIX>
class oomph::PressureBasedSolidExactPreconditioner< MATRIX >
//////////////////////////////////////////////////////////////////////////// ////////////////////////////////////////////////////////////////////////////
The exact solid preconditioner. This extracts 2x2 blocks (corresponding to the displacement/position and pressure unknowns) and uses these to build a single preconditioner matrix for testing purposes. Iterative solvers should converge in a single step if this is used. If it doesn't something is wrong in the setup of the block matrices.
