Detailed Description

Class NonlinearBVPOperator is meant to wrap a pointer to a nonlinear volume or interior spatial operator with a pointer to a BoundaryOperator that handles spatial surface boundary conditions. The constructor takes a pointer to a BVPOperatorParameters object

  1. name: VolumeOperator, type: string, (required), name of the database associated with the volume operator

Member Function Documentation

◆ apply() [1/2]

void AMP::Operator::NonlinearBVPOperator::apply ( AMP::LinearAlgebra::Vector::const_shared_ptr  ,
AMP::LinearAlgebra::Vector::shared_ptr   
)
override

The apply function for this operator performs the following operation: r = b*f+a*A(u), if f is not NULL and r = a*A(u), if f is NULL Here, A represents the action of the composite volume and boundary operator

◆ apply() [2/2]

virtual void AMP::Operator::Operator::apply ( std::shared_ptr< const AMP::LinearAlgebra::Vector u,
std::shared_ptr< AMP::LinearAlgebra::Vector f 
)
pure virtualinherited

This base class can not give a meaningful definition of apply. See the derived classes for how they define apply. Each operator is free to define apply in a way that is appropriate for that operator.

Parameters
ushared pointer to const input vector u
fshared pointer to output vector storing result of applying this operator

Implemented in AMP::Operator::RadDifOp, AMP::Operator::RadDifOpPJac, AMP::Operator::FunctionOperator, AMP::Operator::MemorySpaceMigrationLinearOperator, and AMP::Operator::MemorySpaceMigrationOperator.

virtualinherited

This function returns a OperatorParameters object constructed by the operator which contains parameters from which new operators can be created. Returning a parameter object instead of an Operator itself is meant to give users more flexibility. Examples of how this functionality might be used would be the construction of Jacobian, frozen Jacobian, preconditioner approximations to the Jacobian, adjoint operators etc

Parameters
typestd:string specifying type of return operator parameters being requested. Currently the valid option is Jacobian
uconst pointer to current solution vector
paramspointer to additional parameters that might be required to construct the return parameters
