Hi Umut,

The msh format already stores the partition number for the elements.  
You can work backwards from there to get the node numbers.  
Alternatively, you can write a cgns file in which case the partitions 
are written as separate zones with the associated connectivity -- but 
you have to compile from source to enable cgns I/O.
