Public Member Functions inherited from Opm::WellContributions
unsigned int	getNumWells ()

void	addNumBlocks (unsigned int numBlocks)
	Indicate how large the next StandardWell is, this function cannot be called after alloc() is called.

void	alloc ()
	Allocate memory for the StandardWells.

virtual	~WellContributions ()=default
	Empty destructor.

void	setBlockSize (unsigned int dim, unsigned int dim_wells)
	Indicate how large the blocks of the StandardWell (C and B) are.

void	setVectorSize (unsigned N)
	Set size of vector that the wells are applied to.

void	addMatrix (MatrixType type, int colIndices, double values, unsigned int val_size)
	Store a matrix in this object, in blocked csr format, can only be called after alloc() is called.
