DIANA (DIsplacement ANAlyzer) is an extensive multi-purpose finite element software package that can be utilised in a wide range of engineering sectors.

DIANA FEA BV produces world-class software products and services in the field of Finite Element Analysis (FEA) for a wide range of engineering sectors.

We develop and deliver high-end nonlinear solutions focusing on concrete and its interaction with soil, to help our customers and partners solve advanced engineering challenges. With DIANA 3D simulation models, engineers build safer, cost effective and more robust constructions.

Commitment to high standards sets us apart!

DIANA FEA (previously TNO DIANA ) is a spin-off company from the Computational Mechanics department of TNO Building and Construction Research Institute in Delft, The Netherlands.

We develop and deliver innovative nonlinear simulation software and value-added services including technical support, training, analysis consultancy and R&D projects. DIANA, the flagship software for advanced calculations, is world renowned as the finest in its class, as the “all in one” solution for Finite Element Analysis.

Mission & Vission

We make an impact

Our mission is the optimal and responsible exploitation of constructions during their entire lifecycle based on an understanding of structural behaviour. Our vision is making the DIANA Software the industry standard for nonlinear Finite Element Analyses of civil structures around the world.

Creating concrete insights

We deliver nonlinear solutions to help engineers solving complex challenges!

We are more than just a finite elements analysis software company

With advanced calculations focusing on concrete and its interaction with soil, engineers are able to better understand the behavior of structures. DIANA creates concrete insights to help our customers building a better world.

We are a diverse team of highly skilled professionals

We have a passion for our work, and a strong team spirit based on shared common values:

  • Reliable: Working to build an innovative state-of-the-art software package providing its users with consistent and reliable results
  • Collaborative: Creating a collaborative and engaging work environment that stimulates teamwork and contributes to personal development

Leading companies are using DIANA

"DIANA is able to solve the most complex models, we cannot find any other solutions close to the reality. For nonlinear analysis, DIANA is the way to go for us".

The history of the company

DIANA has a strong heritage that dates back to the 1970s within the renowned Dutch institute for applied scientific research TNO, in which decades have been devoted to developing the software. In 2003 the DIANA software was spun off into a private company called TNO DIANA B.V.

In 2016, the company changed its name to DIANA FEA B.V. to put more emphasis on the DIANA software. In 2021, DIANA FEA became completely independent from TNO and envisages to position itself as a commercial company towards the future.

DIANA is expanded with further functionality

User-supplied subroutines, sequential linear analysis and reinforcement grid design checks

Sales and marketing activities in conjunction with MidasIT are ceased and focus is placed on the continuing development and sales of DIANA

Technical leap forward with the introduction of reinforcement design checks and stiffness adaptation analysis modules, allowing engineers to predict crack patterns, the size of crack openings, plasticity onset, force distribution and deformations in serviceability limit states.
