Re: OpenFOAM .com vs .org

The .extend is a more academic aproach and open to new software for
special purpose CFD problems. It is led by prof Hrvoje Jasak. The .org
is a more conservative aproach and more a top-down managed.

Some years ago I collaborated with Michael Wild in the FreeFOAM project
that converted the .org software with the CMake configuration software
and some other bits to get it easier adapted into the Debian system.
Unfortunately the upstream developers refused to include the
improvements. Finally we left the FreeFOAM project as it included too
much work to keep up with the upstream code.

Therefore all my respect for the developer(s) who continue to include
the OpenFOAM into Debian.
