Hi,
thanks for the fast reply.
Here the files - it's just a simple cube
fun.ele:
6 4 0
1 6 7 1 5
2 1 8 3 4
3 3 7 1 2
4 1 7 6 2
5 1 7 3 8
6 7 8 1 5
# Generated by tetgen -pg fun.poly
fun.node:
8 3 0 0
1 0 0 0
2 1 0 0
3 1 1 0
4 0 1 0
5 0 0 1
6 1 0 1
7 1 1 1
8 0 1 1
# Generated by tetgen -pg fun.poly
fun.face (I don't think you need this one but anyway):
12 0
1 1 2 3
2 6 5 7
3 3 4 1
4 6 2 1
5 7 5 8
6 3 2 7
7 1 5 6
8 8 4 3
9 7 2 6
10 8 5 1
11 7 8 3
12 1 4 8
# Generated by tetgen -pg fun.poly
I'll look at the debugging soon ...
