template<class TypeTag >

void Ewoms::Linear::ParallelAmgBackend< TypeTag >::setStructureMatrix ( const Matrix &  M )

inline

Set the structure of the linear system of equations to be solved.

This method allocates space an does the necessary communication before actually calling the solve() method. As long as the structure of the linear system does not change, the solve method can be called arbitrarily often.

template<class TypeTag >

bool Ewoms::Linear::ParallelAmgBackend< TypeTag >::solve ( const Matrix &  M, Vector &  x, Vector &  b  )

inline

Actually solve the linear system of equations.

Returns

true if the residual reduction could be achieved, else false.
