Detailed Description

Class JacobianOperator provides an abstract interface for the specification of general operators to compute Jacobian-vector products, i.e., $ F'[x]v $.

Member Function Documentation

◆ formJacobian()

virtual void IBTK::JacobianOperator::formJacobian ( SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &  x)
pure virtual

Compute hierarchy dependent data required for evaluating F'[x].

Parameters
xvalue where the Jacobian is to be evaluated

Implemented in IBTK::PETScSNESJacobianJOWrapper, and IBTK::PETScMFFDJacobianOperator.

◆ getBaseVector()

virtual SAMRAI::tbox::Pointer<SAMRAI::solv::SAMRAIVectorReal<NDIM, double> > IBTK::JacobianOperator::getBaseVector ( ) const
pure virtual

Return the vector where the Jacobian is evaluated.

Note
Implementations of this member function are permitted to return a NULL pointer if the operator is not initialized, or if formJacobian() has not been called.

Implemented in IBTK::PETScSNESJacobianJOWrapper, and IBTK::PETScMFFDJacobianOperator.
