So far so good. Are we truly willing to change our mind?

How about the idea to CHANGE both nowadays FDM and FEM methods?

In fact, nowadays FVM and FEM represent totally different _cultures_,
and it's very difficult, sometimes even dangerous, to cross over from
one champ to the other. But perhaps _that_ should represent a challenge
for everybody who is working in the field. Or are we too "pragmatic",
too busy with our "demanding applications" to consider such a thing?

SUNA = Series on Unified Numerical Approximations.

Numerical methods are not a gift from the gods. They were invented by
humans, and the same humans are free to change the boundary conditions.

SUNA articles are available now on a (more or less) permanent basis, via
"anonymous ftp". They can be retrieved as follows:

   ftp dutrde1.tudelft.nl          (: internet-adress = 130.161.180.13)
   Name:                           (: "anonymous")
   Password:                       (: <user>@<host> )
   cd pub/suna
   ls                              (: list of "suna*.net" articles)
   mget <filenames>

See also "SUNA, Published so far" for the complete list of available articles;
it is contained in the file: "sunall.net". Not everything may be of interest.
Articles may be outdated and sometimes even wrong. Start with "The Manifesto".

Gee, it's indeed high time to clean up this stuff ...
