This method extracts the "forward" and "backward" trace data from the array field and puts the data into output vectors Fwd and Bwd.
We first define the convention which defines "forwards" and "backwards". First an association is made between the vertex of each element and its corresponding vertex in the trace space using the mapping m_traceMap. The element can either be left-adjacent or right-adjacent to this trace edge (see Expansion0D::GetLeftAdjacentElementExp). Boundary edges are never left-adjacent since elemental left-adjacency is populated first.
If the element is left-adjacent we extract the vertex trace data from field into the forward trace space Fwd; otherwise, we place it in the backwards trace space Bwd. In this way, we form a unique set of trace normals since these are always extracted from left-adjacent elements.
field | is a NekDouble array which contains the 1D data from which we wish to extract the backward and forward orientated trace/edge arrays. |
Fwd | The resulting forwards space. |
Bwd | The resulting backwards space. |
