Great day at Civiele Bedrijvendagen 2026 in Delft, talking real engineering with the next generation of civil engineers.

Maziar Partovi and Jean‑Claude Bauruelle are at the DIANA booth today and tomorrow, answering questions, walking through real project applications, and showing how advanced FEA and AI‑driven modelling fit into future practice. Thanks to everyone who has already stopped by; we’ve really enjoyed the discussions and are looking forward to more conversations tomorrow.

Water compressibility in dam seismic analysis is not a theoretical detail.
It directly affects the accuracy of hydrodynamic force estimations and the reliability of your structural assessment.

In this article, our team explores how modeling water as compressible versus incompressible impacts dynamic analysis results for dams in seismically active regions, including the effect of boundary conditions, fluid-structure coupling, and excitation frequency proximity to the reservoir's natural frequency.

In reality, seismic forces, hydrodynamic pressures, and foundation responses occur simultaneously.

DIANA captures this interaction through fully coupled fluid–structure modeling, producing results that closely represent the true behavior of dams during seismic events.

True dam behavior under seismic loading is governed by fluid–structure interaction.
DIANA brings this to the forefront through fully coupled FSI, solving the dam, foundation, and reservoir as a single, integrated system, resulting in simulations that capture real physical behavior and give engineers confidence in seismic performance assessments.

Heading to CBD2026? Let’s talk real engineering!

Join us at the Civiele Bedrijvendagen 2026 (Civil Business Days 2026) and discover what the future of civil and geotechnical engineering looks like.

At DIANA FEA B.V., we’re excited to meet students who are curious about pushing boundaries.
Come explore how advanced software development and AI-driven modeling are transforming the industry—and how you can be part of it.

Let’s connect, exchange ideas, and shape the next generation of engineering together.
See you on May 12 at the Aula – Auditorium Conference Center.

Cracking in early-age concrete does not happen randomly. It starts in the first hours after casting, driven by heat, restrained deformation, and material properties that are still evolving.

Read the full article and see how DIANA bridges the gap between monitoring data and reliable numerical prediction.

Can your models handle a sudden structural failure?

In progressive collapse analysis, the real challenge is how a structure redistributes loads after damage. Simple tools often fail once material peaks, but DIANA excels here.
Its stable nonlinear solvers are specifically designed to follow post-peak behavior and softening with precision.

Whether you are simulating a column removal or studying disproportionate collapse, you can capture the complex failure sequences and energy dissipation that define true structural robustness.
Stop guessing how a building survives: start modeling it.

Test the robustness of your designs.

DIANA bridges the gap between code requirements and real-world performance by allowing you to move beyond "pass/fail" checklists.

Instead of following rigid formulas, you can simulate the true nonlinear response of the entire system, optimizing material efficiency and mastering complexity that prescriptive rules simply cannot capture.

Ensuring the resilience of modern infrastructure means moving beyond basic compliance and understanding the physics behind the design.

It is the only way to have total confidence in your structural performance assessments and long-term durability.

Experience the precision of DIANA for yourself by requesting a trial version today.

From June 1st to June 12th, Dr. Denise Ferreira, Dr. Jean-Claude Bauruelle, and Dr. Jingming Ruan will lead a 6-module online technical course on the Nonlinear Behavior of Reinforced Concrete Structures.

This training follows a structured workflow covering the application of the finite element method, with a specific focus on concrete crack models and failure mechanisms.

Gain hands-on experience in choosing the correct crack models, setting convergence criteria, and practicing within the DIANA environment to earn your official certification.

Flexible registration is available for individual modules or the full course, with 6 KE/PE-points available for professional development.
