static const IdxVector< (InDim>OutDim ? InDim+1 : dim-InDim) > RefElement< dim >::interact ( TInteraction< OutDim, InDim > interaction )

static

Usage: RefElement<3>::interact(Interaction<2,0>(1)) (means: In tetrahedron <3>, give indices of sides <2>, connected by node <0> with index 1) RefElement<3>::interact(Interaction<2,0>(1))[1] (as above, but give only the side with index 1)

Template usage: RefElement<dim>::interact(Interaction<OutDim, InDim>(i))[j] (means: on dim-dimensional reference element, go on InDim-dimensional subelement with index i, which connects OutDim-dimnesional subelements and select the one with index j)

This method serves as an interface to topology information of the reference element. It returns indices of OutDim-dimensional object of InDim-dimnesional object of given index in dim-dimnesional reference element.

Template Parameters

interaction	- auxilliary object carying the index and the template arguments OutDim and InDim
OutDim	- output dimension (give me node-0, line-1, side-2), <= dim
InDim	- input dimension (for node-0, line-1, side-2), <= dim

Returns: vector of indices of OutDim-dimensional subelements represented by IdxVector object.

possible calls: dim OutDim InDim return 1,2,3 0 1 InDim+1 - give me indices of nodes of line of given index 3 0 2 InDim+1 - give me indices of nodes of a side (triangle) of given index 3 1 2 InDim+1 - give me indices of lines of side (triangle) of given index

1,2,3 1 0 dim-InDim - give me indices of lines with common node of given index 3 2 0 dim-InDim - give me indices of sides (triangles) with common node of given index 3 2 1 dim-InDim - give me indices of sides (triangles) with common line of given index
