Function Documentation

isInterior()

template<class Intersection >

bool Dune::ACFem::isInterior

(

const Intersection &

intersection

)

Return true if there is a neighbor.

Note that this function will return false if there is a neighbor on another computing node, but ghost-cells are unavailable.

isPeriodicBoundary()

template<class Intersection >

bool Dune::ACFem::isPeriodicBoundary

(

const Intersection &

intersection

)

Return true if at a periodic boundary.

Note that isInterior() will then also return true.

isProcessorBoundary()

template<class Intersection >

bool Dune::ACFem::isProcessorBoundary

(

const Intersection &

intersection

)

Retrun true if at the border to another computing note.

Note that isInterior() may or may not return true int his case.
