Detailed Description

Class to encapsulate fine-level tangential gradient stencil computation.

This is a helper class which essentially wraps three IntVectSets which define which type of stencil to use in computing fine-level tangential gradients. This is only relevant in the presence of a physical boundary (since the only place where the fine-level stencil is shifted is at a physical boundary; in a periodic world, all differences are centered.)

	)

define function

const IntVectSet& TensorFineStencilSet::getCenteredStencilSet

(

int

a_tanDir

)

const

accessor

accessor -- returns cells where fine-level tangential gradient in a_tanDir direction will use a centered-difference stencil. If a_tanDir is normal to the face (i.e, isn't a tangential direction after all), will return an empty IntVectSet.

const IntVectSet& TensorFineStencilSet::getForwardStencilSet

(

int

a_tanDir

)

const

accessor

accessor -- returns cells where fine-level tangential gradient in a_tanDir will use a forward-difference stencil. If a_tanDir is normal to the face (i.e. it isn't a tangential direction after all), will return an empty IntVectSet.

const IntVectSet& TensorFineStencilSet::getBackwardStencilSet

(

int

a_tanDir

)

const

accessor

accessor -- returns cells where fine-level tangential gradient in a_tanDir will use a backward-difference stencil. If a_tanDir is normal to the face, will return an empty IntVectSet.
