Hi David,
The boundary conditions are described for each direction separately. For
example, there may be an i-surfice at i=64, j=1 to 12 and k=23 to 74,
with normal = -1 and boundary conditions type 7:
i-surfaces imin imax jmin jmax kmin kmax normal bc_type
....
7 64 64 1 12 23 74 -1 7
8 1 1 1 49 1 128 1 2
....
where i-surfaces is just a sequential bc_surface tag. I would like to be
able to tag the surface points with both i-surface and with bc_type
property tags. The reason I need this is that I have 1/8 of the grid for
an axial-symetric problem. Now I need to restore the full grid along
with the boundary conditions. Because I am at the beginning of the work
I am trying to foresee some usual problems with generation of a grid and
to build a tool that will make debugging of this process easier.
Thanks,
Ted
