Limited_Quadfit()

template<int D, typename MeshType , typename StateType >

Portage::Limited_Quadfit< D, Entity_kind::CELL, MeshType, StateType >::Limited_Quadfit ( MeshType const &  mesh, StateType const &  state, std::string const  var_name, Limiter_type  limiter_type, Boundary_Limiter_type  Boundary_Limiter_type  )

Constructor.

Parameters

[in]	mesh	Mesh class than one can query for mesh info
[in]	state	A state manager class that one can query for field info
[in]	var_name	Name of field for which the quadfit is to be computed
[in]	limiter_type	An enum indicating if the limiter type (none, Barth-Jespersen, Superbee etc)
[in]	Boundary_Limiter_type	An enum indicating the limiter type on the boundary

Todo:

must remove assumption that field is scalar

Functor.

Implementation of Limited_Quadfit functor for CELLs Limited _Quadfit - Fit to a field to a quadratic multinomial using a Least-Squared fit. Returns an array of parameters. If the CELL is on a boundary the stencil is too small, so it drops to linear order. Uses an SVD decomposition for the LS regression.

Todo:

: must remove assumption the field is scalar

Assignment operator (disabled)

Todo:

Seems to be needed when using this in a Thrust transform call?
