[petsc-users] how to output components of a section

[leejearl]

Hi, all:

     I meet a problems which I can not overcome. The programe is like 
the code in

"http://www.mcs.anl.gov/petsc/petsc-current/src/dm/impls/plex/examples/tutorials/ex1.c.html".

    The code create a section which has three fields: u,v,w. How can I 
output the fields u and v without together with w?

    Thanks!
