What Diana FEA does
Diana FEA B.V. is a Netherlands-based software company headquartered in The Hague that develops DIANA (DIsplacement ANAlyzer), a multipurpose finite element analysis (FEA) package for civil, structural, geotechnical, earthquake, and petroleum engineering. The software originated from the Computational Mechanics department of TNO Building and Construction Research Institute in Delft in the 1970s and was established as Diana FEA in 2003. The platform combines a DIANA Interactive Environment (DIANAIE) for 2D/3D pre- and post-processing with a solver covering linear and nonlinear static, dynamic, modal, spectral, buckling, heat transfer, groundwater flow, and coupled thermo-stress analyses. Its competitive position rests on specialized constitutive models for reinforced concrete (total-strain crack, multi-directional fixed cracking, bond-slip, creep and shrinkage), soil and rock (consolidation, liquefaction models such as UBC, Bowl, Nishi, Towhata-Iai), masonry (Engineering Masonry Model), and advanced procedures such as hybrid frequency-time domain (HFTD) seismic analysis. A Revit Plugin and Python parametric scripting provide CAD/BIM interoperability with formats including IGES, STEP, IFC, DXF, and DWG.
Diana monetizes through subscription-based annual licensing structured into a core EXPERT module plus add-on GEOTECH, STRUCTURAL, and DYNAMICS modules, sold as a FULL Package to enterprise customers and as separate Commercial, Academic, and Research license tiers. Pricing is quote-based and varies by sales region; license keys are issued via Softlock digital activation. Adjacent revenue streams include fee-based training (EUR350 per module, EUR1800 for a full course), paid and free technical webinars, premium technical support with model investigation services, and customized software development. Go-to-market is sales-led, supported by an international partner network (JIP Techno Science in Japan, Next Technology in Korea, DUNPU in China, 2SI in Italy, Geodestek in Turkey, and Rocscience Latin America in Peru), conference participation at events including NAT, ICOLD, WTC, CBD, USSD, and ACI Concrete Convention, and content marketing via technical publications, whitepapers, and a YouTube channel. Since January 2024 the company has operated as a subsidiary of Canada's Rocscience Inc., which acquired it to expand structural and civil engineering capabilities. The firm serves engineers and researchers in structural and construction, hydropower and energy (including dams, nuclear, and oil and gas), underground structures (tunneling and geotechnical), and masonry and historical preservation segments.
