OOFEM has been under continuous development since 1997. 
The project started in 1993 as part of Borek Patzak PhD thesis on computational modeling
of concrete structures. The initial source of inspiration at the
beginning (1993), was [[http://www.zace.com/femobj.htm|FEM_Object]]
program, written by T. Zimmermann and Y. Dubois-Pelerin, from which some
ideas and routines are used.

Since then, the code has been further developped at Cech Technical University in
Prague, Faculty of Civil Engineering, [[http://mech.fsv.cvut.cz/web/index.php?&lang=en|Department of Mechanics]].
In 2001 the project has been officially released under open-source
licence and many developpers and users around the world have joined
the OOFEM comminity and contributed to its development.
