[Gmsh] cgns reader

[Umut Tabak]

Dear all,

My question is not directly on gmsh however since I save the cgns file 
from out of gmsh, it is best to ask it also here.

I am using gmsh to partition some mesh structure(that is a native Ansys 
mesh structure) and then would like to read the related element and node 
information related to these partitions. I can save the mesh as a cgns 
file from and should use the cgns library, I took a look at the cgns 
manual on the cgns web page, there are some pointers on how to read data 
and some example source code. However, I was wondering if there is 
already a code that reads these partitions and related information, as 
mentioned above, I also found a mex interface to MATLAB but before 
diving in, I would like to ask if there are some better pointers for 
starting out?

Best,
Umut
