Description

GRIDBDRE Generate grid edge boundary information.

[ BE, E, EV ] = GRIDBDRE( B, C ) Given arrays B and C with cell connectivities and face boundary information generates an array with edge boundary information.

Input       Value/(Size)           Description
-----------------------------------------------------------------------------------
b           (3/6,n_b)              Array with boundary information, the first row
                                   indicates the cell number, followed by cell
                                   face, boundary number, and optionally the
                                   normal vectors for each boundary face
c           (n_pcell,n_cells)      Cell connectivity pointer array where the
                                   entries in each column correspond to the
                                   cell vertex numbers.
                                                                                  .
Output      Value/(Size)           Description
-----------------------------------------------------------------------------------
be          (5,n_b)                Array with boundary information, the first row
                                   indicates the global cell number, followed by
                                   local cell face, local edge, and global edge
                                   and edge boundary numbers.
e           (n_e,n_c)              Array with global edge numbers for all cells.
ev          (n_e,2)                Array with indices to vertices for each edge.
