No. Even though you give the grompp output, you haven't told what you tried to do, which force field you're using and what you did to come to this stage. We can't guess what's in you're topology file. You also clearly haven't searched the archive for posts on "No default ... types", and thus give the impression that you think of us as some helpdesk you've paid for. Please first read the following page, search the wiki (http://wiki.gromacs.org/) and the archives of the user list.
