DIANA (acronym DIsplacement ANAlyser) is a Finite Element Analysis (FEA) solver developed and distributed by DIANA FEA BV (previously TNO DIANA BV) and several other resellers worldwide. The software is utilised at both ends of the market, by small consultancies and global engineering consultants, research institutions and is utilised by many highly respected educational institutions worldwide in both civil and geotechnical engineering courses. DIANA is equipped with very powerful solvers which enables the analysis of a wide range of structures, large and small - with basic or advanced analyses. A large selection of material models, element libraries and analysis procedures are available within the package which gives DIANA a large degree of flexibility. The main fields of use of DIANA include design and analysis of dams & dikes; tunnels & underground structures; oil & gas[1] & historical constructions and large reinforced concrete structures.[2] Some of the specialised analyses available in DIANA for these fields of use include seismic analysis;[3] fire analysis and young hardening concrete.[4]
History
1970s to 1980s
TNO (Netherlands Organisation for Applied Scientific Research) originally authored the code,[5] upon which the DIANA FEA BV flagship software “DIANA” is based, in 1972. The initial idea had been to develop an in-house code for consultancy work in the field of concrete mechanics and civil engineering. This code was based on the displacement method, and was called “DIANA” – an acronym for DIsplacement ANAlyser. By 1975, DIANA was being used for the analysis of a number of complex off-shore structures in the Netherlands. Experience gained from these projects led to the realisation that in order to model, mesh and analyse large reinforced concrete structures in a streamlined fashion (and within one package), a huge amount of processing power would be required. At that point TNO started to invest in not only developing the DIANA software but also in the purchase of, what was then, up to the minute computing equipment. In the following years, TNO continued to expand the limitations of the DIANA software, introducing MESH for automatic mesh generation and GRAPHI to display the model and analysis results. In 1977, DIANA was used to analyse parts of the Oosterschelde Deltawerken in Zeeland, the Netherlands. By this time, the amount of time required to carry out analyses had significantly decreased, and DIANA was becoming increasingly recognised for its capabilities.
1980s to 1990s
The first release of DIANA, “DIANA-1”, was made available to the Ministry of Public Works in the Hague (Rijkswaterstaat) in 1980. The result of this and more sales, further funding and development took place and in 1984 the DIANA Users Association was established. This users forum was established to, and continues to, provide an exchange of users experience and indicate development priorities to TNO (now to DIANA FEA BV). Release 2.0 of DIANA was made available in 1988, this included new modules for potential flow analysis and connection to external pre/post processors. For the first time users manuals, course books and text books were made available in English – this quickly led to the first sales of DIANA outside of the Netherlands. In 1989, the DIANA Foundation was formed, members included TNO’s major partners (a combination of universities, research institutes and industrial partners). The Foundation was granted access to the DIANA source code thus enabling them to further develop DIANA. It became the role of TNO to transfer these developments into the production version of DIANA.
1990s to 2003
Between 1990 and 2003, with continuing development and input from the Users Association and the DIANA Foundation, DIANA became recognised worldwide for its analysis capabilities. DIANA Analysis BV was established to manage the sales, marketing, promotion and support of DIANA. In the late 1990s FEMGV (produced by FEMSYS Ltd (UK)) was introduced and promoted by TNO as a pre/post processor which could be coupled to DIANA providing an interactive graphical interface. In the early 2000s, FEMGV was embedded into the DIANA programme and became known as iDIANA and distributed as part of the DIANA package. FEMGV continued to be sold separately by TNO (and now TNO DIANA BV). In October 2002 the Third DIANA World Conference[6] took place in Tokyo. By this time, Japan had become the most important export market for DIANA. The emphasis of the conference was on application of advanced computational models in civil engineering applications.
2003 to present
In 2002 TNO prepared a new organization around DIANA: a company named TNO DIANA BV was founded and in the beginning of 2003 all technical activities were transferred from TNO Building and Construction research to the new company. Also the marketing and sales activities, until then being done by DIANA Analysis BV, were transferred to TNO DIANA BV. At the same time TNO DIANA BV became owner of Femsys Ltd. The purpose for creating this new organization was to combine commercial and technical activities and to have full focus to needs of DIANAusers world-wide.
Between 2006 and 2011, TNO DIANA BV established a relationship with the Korean software developer MIDAS. In conjunction with MIDAS, the FX+ for DIANA pre/post processor was developed for use specifically with DIANA and was sold as an additional option to purchasers. In return, TNO DIANA BV helped MIDAS embed elements of DIANA into their midasGTS product as its solver. During this period, TNO DIANA BV was also a reseller of MIDAS products: midasCIVIL; midasFEA; midasGEN; and midasGTS. At the end of 2011, following the completion of the FX for DIANA and midasGTS projects, the relationship between TNO DIANA BV and MIDAS was distanced allowing each company to concentrate on the sales and development of their own products.
In January 2012 came the next iteration of the DIANA software, DIANA 9.4.4. Two new application modules were made available which signified a leap forward in the analysis of reinforced concrete.
The module “Reinforcement Design Checks” gave civil engineers the opportunity to optimise the design of structures by assessing the additional capacity within the existing reinforcement. Running alongside this, the new module “Stiffness Adaptation Analysis” made it possible to predict crack patterns, the size of crack openings, plasticity onset, force distribution and deformations in serviceability limit state.
For geotechnical engineers the ability to carry out a Strength Reduction Analysis (C-Phi) was made available in a new module. This allowed the strength characteristics of the structural material to be reduced by factors leading to the loss of stability, typically used in slope stability analysis. In 2014 there were two releases of DIANA (9.5 & 9.6), these releases introduced the new Mesh Edit graphical user interface. With the ultimate goal of providing TNO DIANA’s own integrated graphical user interface. Mesh Edit offers a streamlined and user friendly interface which will ultimately enable users to use all the functionality of DIANA within one program.
The initial iteration of MeshEdit gave the users the ability to import their model from FX+ or iDIANA and then define supports, loading, materials and analysis requirements; carry out the analysis; and deal with post processing. In 9.6 these features were extended to include a Python scripting console, the introduction of mesh sets and further post processing functionality.
DIANA 10.1, is released in late 2016, with improved integration of modelling, meshing and analysis in one unique, and integrated, environment. This platform has been empowered by use of a parasolid geometry modeller and the latest generation of hexa dominant mesh engine. New post-processing features enable the user to interpret and visualise the results in a very flexible post-processing environment.
On 1 July 2016, TNO DIANA BV changed its name to DIANA FEA BV "to reflect the name of the product and place more emphasis on DIANA rather than its ties to TNO".
