I'm curious:

In the current state of the OpenFOAM Wikipedia entry[1] it says:

"Original author(s): Henry Weller"

Can some of the foam'ers who have been around since the beginning please enlighten me. Is this the truth, the whole truth and nothing but the truth?

Hi,

well Henry Weller was the first person who developed FOAM
a brief history of FOAM or OpenFOAM that leaves out the name of (Prof.) Hrvoje Jasak can be read http://cfd.direct/openfoam/
another story on OpenFOAM including the the name of Hrvoje Jasak one of the first persons working on the development of FOAM or OpenFOAM can be read
http://wikki.gridcore.se/company/about-us

some authors are listed
http://www.openfoam.org/version2.3.1/
OpenFOAM v2.3.1 was produced by Henry Weller, Mattijs Janssens, Chris Greenshields, Andy Heather, William Bainbridge and Sergio Ferraris. Thanks to the OpenFOAM enthusiasts who have contributed to a better code through the bug reporting system.

for the OF-extend world you can see the contributors (see file ListOfContributors),
http://sourceforge.net/p/openfoam-ex...OfContributors

Do you point on those posts as you ask for the original author?

I can easily give you three pieces of evidence that Mr. Weller tries to suppress every day since 2004:

My PhD Thesis: Jasak, H.: Error analysis and estimation in the Finite Volume method with applications to fluid flows, Imperial College, University of London, 1996

A company called Nabla Ltd, the actual owner of the FOAM source code (Companies House, 2000-2006, number 3775453.

foam2.3.2: copyright statement, authorship signatures in the source code and list of contributors.

Also, have a look at OpenFOAM-1.0 list of contributors and notice how it misteriously disappeared (in violation of GPL, that we hear so much about):

10. List of Contributors
~~~~~~~~~~~~~~~~~~~~~~~~
Henry Weller
Hrvoje Jasak
Chris Greenshields
Mattijs Janssens
Niklas Nordin
Eugene De Villiers
Gavin Tabor
Zeljko Tukovic
Tommaso Lucchini
David Hill
Niklas Wikstrom
Hilary Spencer
Andy Heather
Henrik Rusche

I guess that's enough for the moment. There is also a bunch of legal docs, but I don't think you are that much interested...

Thanks for your replies Elvis and Hrvoje.

Just for the fun of it I downloaded the first and last foam version made public by powerlab and counted the number of occurences of "Jasak" and "Weller" in the source code:

wget http://powerlab.fsb.hr/ped/kturbo/Op...6_19_01_01.tgz
tar -xzf foam1.9.6_19_01_01.tgz

wget http://powerlab.fsb.hr/ped/kturbo/Op...3_28_10_04.tgz
tar -xzf foam2.3_28_10_04.tgz

and then:

find foam2.3 -name "*.[H,C]" | xargs grep -i "Jasak" | wc -l
1098
find foam2.3 -name "*.[H,C]" | xargs grep -i "Weller" | wc -l
2076

find foam1.9.6 -name "*.[H,C]" | xargs grep -i "Jasak" | wc -l
62
find foam1.9.6 -name "*.[H,C]" | xargs grep -i "Weller" | wc -l
1163

Whatever that tells...

I guess it all comes down to the exact definition of "Original author(s)" of an ever evolving source code.

Anyway, it seems strange to me that the only names mentioned in the "History" section of the Wikipedia OpenFOAM entry are Henry Weller, Chris Greenshields and Mattijs Janssens.

Cheers,
Johan
