Detailed Description

Fourth-order interpolation in time and space to ghost cells.

Constructor & Destructor Documentation

NWOQuadCFInterp::NWOQuadCFInterp ( )
inline

Default constructor.

Object requires define() to be called before all other functions.

References m_defined.

NWOQuadCFInterp::NWOQuadCFInterp ( const DisjointBoxLayout a_thisDisjointBoxLayout,
const DisjointBoxLayout a_coarserDisjointBoxLayout,
const int &  a_numStates,
const ProblemDomain a_coarseDomain,
const int &  a_refineCoarse,
const int &  a_interpRadius 
)
inline

Full constructor.

Parameters
a_thisDisjointBoxLayoutlayout at this level
a_coarserDisjointBoxLayoutlayout at coarser level
a_numStatesnumber of variables
a_coarseDomainproblem domain on the coarser level
a_refineCoarserefinement ratio between this level and the coarser level
a_interpRadiusnumber of layers of ghost cells to fill by interpolation

References define().

NWOQuadCFInterp::~NWOQuadCFInterp ( )
inline

Destructor.

Destroys all objects created by define(). Passed in data references of define() are left alone.
