DIANA FEA 10.10, the latest release from DIANA FEA BV as of July 2025, is a multi-purpose finite element analysis (FEA) software tailored for civil, geotechnical, structural, and earthquake engineering, with applications in tunnels, dams, bridges, and oil & gas structures. Below is an overview of its key features and updates based on available information:

Key Features of DIANA FEA 10.10

  • Advanced Material Models: Supports extensive material libraries, including concrete, steel, reinforcement, soils, and rocks, with models like Hardening Soil, Modified Mohr-Coulomb, and Maekawa-Fukuura for concrete. It handles linear and nonlinear behaviors for complex geotechnical and structural analyses.
  • 2D and 3D Modeling: Offers robust modeling capabilities with full CAD/BIM interoperability, enabling seamless integration with tools like AutoCAD, Parasolid, and Midas FX+. It supports STEP/IGES file imports for enhanced workflow.
  • Geotechnical Capabilities: Includes state-of-the-art constitutive models for soil and rock, covering in-situ stress, pore pressure, consolidation, groundwater flow, and seismic/liquefaction analysis. It excels in modeling foundations, embankments, tunnels, and slope stability.
  • Structural Analysis: Facilitates advanced nonlinear analysis for reinforced concrete, masonry, and steel structures, including seismic, fire, and hydration analyses for mass concrete.
  • Interactive Environment (DIANAIE): Features a user-friendly GUI with meshing tools, geometric primitives (e.g., helix, ellipse), and Python scripting for automation and customization.
  • Solvers and Analysis Types: Equipped with powerful solvers for linear, nonlinear, static, dynamic, and eigenvalue analyses. It supports modal frequency response, response spectrum, and strength reduction methods.
  • Specialized Applications: Handles complex scenarios like soil-structure interaction, pile foundations, and post-tensioning in reinforcements. It also supports hybrid frequency-time domain analysis and enthalpy-poroelastic analysis.
  • Reporting and Output: Generates automated reports and detailed results for stresses, deformations, pore pressures, and more, with post-processing compatible with tools like ParaView.
