'''DIANA''' (from ''DI''splacement ''ANA''lyser) is a Finite Element Analysis (FEA) solution that does basic and advanced analysis of various structures. DIANA FEA BV (previously TNO DIANA BV) develops software and with several re-sellers, distributes it worldwide. A selection of material models, element libraries, and analysis procedures within the package gives DIANA flexibility. Engineers have used DIANA to design dams and dikes, tunnels and analyse underground structures, oil and gas,<ref>{{Cite book |last=Endal.

== History ==
In 1972, TNO (Netherlands Organisation for Applied Scientific Research) authored the code that would eventually form the basis of the DIANA FEA BV "DIANA" software.<ref>{{Cite web |last=Leemhuis, A.P. |title=Innovative History Matching |url=http://www.tno.nl/content.cfm?context=thema&content=prop_case&laag1=895&laag2=911&laag3=97&item_id=1648&Taal=2 |access-date=29 November 2013}}</ref> The initial idea had been to develop an in-house code for consultancy work on concrete mechanics and civil engineering. This code was based on the displacement method and was called "DIANA", an acronym for '''DI'''splacement '''ANA'''lyser.<ref>{{Cite book |last1=Hordijk |first1=D.

In October 2002 the Third DIANA World Conference<ref>{{Cite book |title=Finite Element in Civil Engineering Applications |date=January 2002 |isbn=978-9058095305 |editor-last=Hendriks, M.A.N. |edition=1st |editor-last2=Rots, J.A.}}</ref> took place in Tokyo.{{citation needed|date=July 2020}}

In 2002, TNO founded TNO DIANA BV to combine commercial and technical activities and to focus on the needs of DIANA users worldwide. Thus, in early 2003, TNO DIANA BV took over technical activities from TNO Building and Construction research, marketing, and sales from DIANA Analysis BV. It also became the owner of Femsys.{{citation needed|date=July 2020}}
