Ted Kord is still having a problem:
No, V's not a vector-valued space.
By duplicates, I mean that the vertices that are on a common edge
between elements are repeated in the enumeration. For example, for a
4x4 rectangle with 2 P2 elements, i.e., nx = ny = 1
Rectangle mesh(0.0, 0.0, 4.0, 4.0, nx, ny)
V.dofmap().tabulate_coordinates(...) produces:
0: (0, 0)
1: (4, 0)
2: (4, 4)
3: (4, 2)
4: (2, 2)
5: (2, 0)
6: (0, 0)
7: (0, 4)
8: (4, 4)
9: (2, 4)
10: (2, 2)
11: (0, 2)
Vertices 0 and 6, 2 and 8, 4 and 10 are repeated.
I'd like to eliminate these without sorting so that the vertices are
still evaluated in the correct order.
Is there already a function to do this or is there a better way?
Ted
