◆ addFieldToEmptyFieldBlocks()

MoFEMErrorCode MoFEM::ProblemsManager::addFieldToEmptyFieldBlocks	(	const std::string	problem_name,
		const std::string	row_field,
		const std::string	col_field
	)		const

add empty block to problem

MatrixManager assumes that all blocks, i.e. all fields combinations are non zero. This is not always the case, to optimise code and reduce memory usage user can specifi which blocks are empty.

Parameters

problem_name	problem name
row_field	row filed name
col_field	col field name

Returns: MoFEMErrorCode

	)

Remove DOFs from problem.

Remove DOFs from problem which are on entities on the given range and given field name. On the finite element level, DOFs can be still accessed however local PETSc indices and global PETSc indices are marked with the index -1.

Note: If the index is marked -1 it is not assembled and dropped by VecSetValues and MatSetValues.

Todo:: Not yet implemented update for AO maps and IS ranges if removed entities in composite problem or sub-problem

Parameters

problem_name	name of the problem
field_name	name of the field
ents	entities on which DOFs are removed
lo_coeff	low dof coefficient (rank)
hi_coeff	high dof coefficient (rank)
verb	verbosity level
debug	to debug and seek for inconsistencies set to true

Returns: MoFEMErrorCode

Note: Use this function for nondistributed meshes

◆ removeDofsOnEntitiesNotDistributed() [2/2]

MoFEMErrorCode MoFEM::ProblemsManager::removeDofsOnEntitiesNotDistributed	(	const std::string	problem_name,
		const std::string	field_name,
		const Range	ents,
		const int	lo_coeff = `0`,
		const int	hi_coeff = `MAX_DOFS_ON_ENTITY`,
		const int	lo_order = `0`,
		const int	hi_order = `100`,
		int	verb = `VERBOSE`,
		const bool	debug = `false`
	)

Remove DOFs from problem.

Remove DOFs from problem which are on entities on the given range and given field name. On the finite element level, DOFs can be still accessed however local PETSc indices and global PETSc indices are marked with the index -1.

Note: If the index is marked -1 it is not assembled and dropped by VecSetValues and MatSetValues.

Todo:: Not yet implemented update for AO maps and IS ranges if removed entities in composite problem or sub-problem

Parameters

problem_name	name of the problem
field_name	name of the field
ents	entities on which DOFs are removed
lo_coeff	low dof coefficient (rank)
hi_coeff	high dof coefficient (rank)
verb	verbosity level
debug	to debug and seek for inconsistencies set to true

Returns: MoFEMErrorCode

Note: Use this function for nondistributed meshes
