There is some melt code mentioned in 

  http://www.geodynamics.org/pipermail/cig-long/2009-October/000246.html

and followup messages.  I have not looked at it at all.

I presented some developer information at the developers workshop.
You can get all of the talks at

If you want to start modifying the code, I would recommend that you
use the Mercurial repositories instead of the Subversion repository.
They have basically the VPAC/Monash code with the Gale enhancements as
I get them done.  Many things have changed, and it is still in a bit
of flux, but I think it is the best code to base any significant
modifications on.

In any case, you can get the code with the commands

  hg clone http://geodynamics.org/hg/long/3D/uworld uworld_walter
  hg clone http://geodynamics.org/hg/long/3D/uworld/PICellerator uworld_walter/PICellerator
  hg clone http://geodynamics.org/hg/long/3D/uworld/StGermain uworld_walter/StGermain
  hg clone http://geodynamics.org/hg/long/3D/uworld/StgDomain uworld_walter/StgDomain
  hg clone http://geodynamics.org/hg/long/3D/uworld/StgFEM uworld_walter/StgFEM
  hg clone http://geodynamics.org/hg/long/3D/uworld/Underworld uworld_walter/Underworld
  hg clone http://geodynamics.org/hg/long/3D/uworld/config uworld_walter/config
  hg clone http://geodynamics.org/hg/long/3D/uworld/gLucifer uworld_walter/gLucifer

Are you thinking of getting started immediately, or will it not be
until later?
