void TFESpace3D::ConstructSpace ( BoundCondFunct3D * BoundaryCondition )

construct space

set clipboard to all bound/interface edges, since only an edge from a cell be on the bound (in particaul Dirchlet)

Finding BD (in particaul Dirichlet) Dof only may miss the edge BD DOF

unfortunately if this processor is the master of the missed BD (in particaul Dirichlet) dof, it will give wrong result

only vert in a cell may be on the BD, so BD vertices also included 30.06.2012, sashi

set dept. vert neib cells to -1, especiall to use own_FEspace and FEspace with (own + Hallo) cells

if Hallo cells in this coll, the it will set to "i", otherwise -1

modified by sashi, since BD is not regular and T, S are not defined when tetgen is used

edges on this face are already set, so no need of checking in BD edges on this face

vertices on this face are already set, so no need of checking in BD vert on this face, 30.06.12, sashi

identify BD edges but not part of BD faces

vertices on this edge are already set, so no need of checking in BD vert on this edge, 30.06.12, sashi

identify BD vert but not part of BD faces/edge

I hope, it is enough to check BD vertices, sice other vertices are anyway inner, so no prob with Dirichlet BD

modified by sashi, since BD is not regular and T, S are not properly defined when using tetgen

edges on this face are already set, so no need to check in BD edges on this face

vertices on this face are already set, so no need to check in BD vert on this face, 30.06.12, sashi

vertices on this edge are already set, so no need of checking in BD vert on this edge, 30.06.12, sashi

identify BD vert but not part of BD faces/edge

I hope, it is enough to check BD vertices, since other vertices are anyway inner, so no prob with Dirichlet BD

fill the already assigned global dof

hallo cell included, as multigrid fespace will contain Halo cells - Sashi:10-03-15

own cell or neib cell (i.e. Hallo cells) is not in this collection

hallo cells are also need to be considered, so modified 11 Mar 2015 by Sashi

own cell or neib cell (i.e. Hallo cells) is not in this collection
