Detailed Description

template<typename DeviceType>
class Intrepid2::RefCellCenter< DeviceType >

This class defines the coordinates of the barycenter of the supported reference cells. The barycenter coordinates are stored in static views. The class is templated on the Kokkos::Device Type which is used to determine layout and memory space of the views.

Member Function Documentation

template<typename DeviceType >

RefCellCenter< DeviceType >::ConstViewType Intrepid2::RefCellCenter< DeviceType >::get ( const unsigned  cellTopoKey )

inlinestatic

Retrieves the Cartesian coordinates of a reference cell barycenter.

Returns Cartesian coordinates of a reference cell barycenter. Requires cell topology with a reference cell. Barycenter coordinates are always returned as an (x,y,z)-triple regardless of the actual topological cell dimension. The unused coordinates are set to zero, e.g., center of Line<2> is returned as {0,0,0}.

Parameters

cell	[in] - key of the cell topology

Returns

a rank-1 Kokkos::View containing the coordinates of the cell nodes The returned view has dimension 3.
