DIANA (from ''DI''splacement ''ANA''lyser) is a Finite Element Analysis (FEA) solver that does basic and advanced analysis of various structures. DIANA FEA BV (previously TNO DIANA BV) develops the software and with several resellers, 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, historical constructions, and large reinforced concrete structures. Some specialised analyses available in DIANA for these fields of use include seismic analysis, fire analysis, and young hardening concrete.

History

In 1972, TNO (

Netherlands Organisation for Applied Scientific Research Nederlandse Organisatie voor Toegepast Natuurwetenschappelijk Onderzoek (TNO; en, Netherlands Organisation for Applied Scientific Research) is an independent research organisation in the Netherlands that focuses on applied science. The organisat ...

) authored the code that would eventually form the basis of the DIANA FEA BV "DIANA" software. 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 DIsplacement ANAlyser. In October 2002 the Third DIANA World Conference took place in Tokyo. 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.
