◆ AdditionalPhysicalDataIsNeeded()

template<class TSparseSpaceType , class TDenseSpaceType , class TReordererType = Reorderer<TSparseSpaceType, TDenseSpaceType>>

bool Kratos::MonotonicityPreservingSolver< TSparseSpaceType, TDenseSpaceType, TReordererType >::AdditionalPhysicalDataIsNeeded ( )

inlineoverridevirtual

Some solvers may require a minimum degree of knowledge of the structure of the matrix. To make an example when solving a mixed u-p problem, it is important to identify the row associated to v and p. another example is the automatic prescription of rotation null-space for smoothed-aggregation solvers which require knowledge on the spatial position of the nodes associated to a given dof. This function tells if the solver requires such data

Reimplemented from Kratos::LinearSolver< TSparseSpaceType, TDenseSpaceType, Reorderer< TSparseSpaceType, TDenseSpaceType > >.

◆ Clear()

template<class TSparseSpaceType , class TDenseSpaceType , class TReordererType = Reorderer<TSparseSpaceType, TDenseSpaceType>>

void Kratos::MonotonicityPreservingSolver< TSparseSpaceType, TDenseSpaceType, TReordererType >::Clear ( )

inlineoverridevirtual

This function is designed to clean up all internal data in the solver. Clear is designed to leave the solver object as if newly created. After a clear a new Initialize is needed

Reimplemented from Kratos::LinearSolver< TSparseSpaceType, TDenseSpaceType, Reorderer< TSparseSpaceType, TDenseSpaceType > >.

◆ FinalizeSolutionStep()

		VectorType &	rX,
		VectorType &	rB
	)

inlineoverridevirtual

This function is designed to be called at the end of the solve step. for example this is the place to remove any data that we do not want to save for later

Parameters

rA.	System matrix
rX.	Solution vector. it's also the initial guess for iterative linear solvers.
rB.	Right hand side vector.

		VectorType &	rX,
		VectorType &	rB
	)

inlineoverridevirtual

This function is designed to be called every time the coefficients change in the system that is, normally at the beginning of each solve. For example if we are implementing a direct solver, this is the place to do the factorization so that then the backward substitution can be performed effectively more than once

Parameters

rA.	System matrix
rX.	Solution vector. it's also the initial guess for iterative linear solvers.
rB.	Right hand side vector.
