Recorded Video: Introduction to DIANA and its capabilities

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 utilized at both ends of the market, by small consultancies and global engineering consultants, research institutions and is utilized 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 & historical constructions and large reinforced concrete structures.
