Detailed Description

template<typename Grid, typename GridView>
struct Opm::LookUpCellCentroid< Grid, GridView >

LookUpCellCentroid struct - To search cell centroids via element index.

Instead of using a specialitation for Dune::CpGrid, we implement std::enable_if to overload methods with different definitions: for Dune:CpGrid and for other Grid types. An auxiliary defualt template parameter (GridType = Grid) is added to deal with the dependent names at template instantiation.

const

: Call operator

For grids different from Dune::CpGrid, it takes an element index, and returns its cell centroid, from an EclipseGrid.

Template Parameters

GridType

Auxiliary type to overload the method, distinguishing general grids from CpGrid, with std::enable_if. Default: GridType = Grid.

Parameters

[in]

elemIdx

Element Index.

Returns

centroid Centroid of the element, computed as in Eclipse.

const

: Call operator

For Dune::CpGrid, it returns a function, taking an integer, returning cell centroid, computed as in Eclipse.

Template Parameters

Returns

centroid Element centroid, computed as in Eclipse.
