Public Member Functions inherited from oomph::Preconditioner | |
Preconditioner () | |
Constructor. More... | |
Preconditioner (const Preconditioner &)=delete | |
Broken copy constructor. More... | |
void | operator= (const Preconditioner &)=delete |
Broken assignment operator. More... | |
virtual | ~Preconditioner () |
Destructor (empty) More... | |
virtual void | preconditioner_solve (const DoubleVector &r, DoubleVector &z)=0 |
Apply the preconditioner. Pure virtual generic interface function. This method should apply the preconditioner operator to the vector r and return the vector z. More... | |
virtual void | preconditioner_solve_transpose (const DoubleVector &r, DoubleVector &z) |
Apply the preconditioner. Pure virtual generic interface function. This method should apply the preconditioner operator to the vector r and return the vector z. (broken virtual) More... | |
void | setup (DoubleMatrixBase *matrix_pt) |
Setup the preconditioner: store the matrix pointer and the communicator pointer then call preconditioner specific setup() function. More... | |
void | setup (const Problem *problem_pt, DoubleMatrixBase *matrix_pt) |
Compatability layer for old preconditioners where problem pointers were needed. The problem pointer is only used to get a communicator pointer. More... | |
void | enable_silent_preconditioner_setup () |
Set up the block preconditioner quietly! More... | |
void | disable_silent_preconditioner_setup () |
Be verbose in the block preconditioner setup. More... | |
virtual void | setup ()=0 |
Setup the preconditioner. Pure virtual generic interface function. More... | |
virtual void | clean_up_memory () |
Clean up memory (empty). Generic interface function. More... | |
virtual DoubleMatrixBase * | matrix_pt () const |
Get function for matrix pointer. More... | |
virtual void | set_matrix_pt (DoubleMatrixBase *matrix_pt) |
Set the matrix pointer. More... | |
virtual const OomphCommunicator * | comm_pt () const |
Get function for comm pointer. More... | |
virtual void | set_comm_pt (const OomphCommunicator *const comm_pt) |
Set the communicator pointer. More... | |
double | setup_time () const |
Returns the time to setup the preconditioner. More... | |
virtual void | turn_into_subsidiary_block_preconditioner (BlockPreconditioner< CRDoubleMatrix > *master_block_prec_pt, const Vector< unsigned > &doftype_in_master_preconditioner_coarse) |
Virtual interface function for making a preconditioner a subsidiary of a block preconditioner. By default nothing is needed, but if this preconditioner is also a block preconditioner then things need to happen. There's an assumption here that the block preconditioner will be in CR form but since that assumption is hard coded all over BlockPreconditioner we're safe. More... | |
virtual void | turn_into_subsidiary_block_preconditioner (BlockPreconditioner< CRDoubleMatrix > *master_block_prec_pt, const Vector< unsigned > &doftype_in_master_preconditioner_coarse, const Vector< Vector< unsigned >> &doftype_coarsen_map_coarse) |
Virtual interface function for making a preconditioner a subsidiary of a block preconditioner. By default nothing is needed, but if this preconditioner is also a block preconditioner then things need to happen. Version for coarsening dof-types. More... | |
