Hi Matt,
I try to get the global vertex index and cell index from local
mesh and run into problem. What I need is local to global index
(the original index used in DMPlexCreateFromCellList is best, as
user know exactly where the node/cell is) for vertices and cells,
which will be used to assign material properties and some
parameters to the specified cell/vertex.
I would recommend doing this before you distribute the mesh. Just set
these properties using a DMLabel and it will be automatically distributed.
I will try this. Thanks.
I can use coordinates to select vertex/cell which has already
included, but still want to keep this feature. This is pretty
straightforward when using structured grid. For the unstructured
grid, I just got compiling error saying "You need a ISO C
conforming compiler to use the glibc headers"
For any compilation problem, you have to send the configure.log and
make.log. However, it appears that you are not using the same compiler
that you configured with.
Sorry for confusion. There are linux-gnu-dbg (debug version) and
linux-gnu-opt (optimized version) configuration, the one I used to
compile is debug version and the attached one is optimized version. I
will try you recommendation first.
Thanks,
Danyang

Would you please let me know if I need to change the configuration
of PETSc or is there any alternative ways to avoid using
DMPlexGetVertexNumbering and DMPlexGetCellNumbering but get local
to global index?
The error information during compilation is shown below, followed
by PETSc configuration.
