The OpenGrADS extensions that we just put out with v1.9.0-rc1 have a very
fast dynamic UDF that implements a poisson solver; it is called fish(). The
code actually came out of Mike's psichig classic UDF.

Mike: we need to post documentation for this on the wiki, specially the
periodic boundary condition stuff.

In the meantime take a look at this:

     http://opengrads.cvs.sourceforge.net/opengrads/contrib/extensions/fish/

The script utFish.gs shows how to compute streamfunction/velocity potential
from u and v wind components.  Binaries for the extensions are on sf.net:

   http://sourceforge.net/project/showfiles.php?group_id=161773

Installation instructions are here:

   http://opengrads.org/wiki/index.php?title=User_Defined_Extensions

It comes bundled with the Win32 Superpack.
