VORtech Blog

This is the third blog in our series where we show that our mathematical strengths are an important complement to our programming skills. Using a mathematical approach, we achieve solutions that programming alone couldn't. This time, we talk with Max and Bas who translated the intuition of the net strategists at TenneT into a mathematical optimization problem that can be solved reliably.

As VORtech celebrates its 30-year anniversary, the world of computational software is changing rapidly. The software development process itself is being transformed by AI coding tools, physics-based AI is rapidly establishing itself alongside traditional simulation techniques, hardware is evolving at an unprecedented pace, and quantum computing is emerging on the horizon. At the symposium The Future Is Here on April 9, 2026, VORtech took its relations on a tour across these important developments.

Effective May 1st, Jeroen Gerrits will be the new director of VORtech. After 30 years, the current director Mark Roest is stepping down. In this joint interview, Mark and Jeroen discuss this change.

This year, the TU Delft Institute for Computational Science and Engineering (DCSE) will award a prize for the best MSc-thesis in the field for the first time. VORtech is the proud sponsor of this prize.

Many of our clients are working on software for forecasting or simulating natural processes such as the flow of water and the processes in industrial installations. Given the rapid developments in AI, an obvious question is whether it is also suitable for these calculations with a physics background. The answer is: yes, but…

Our anniversary symposium on April 9th ​​in Delft will discuss the big changes in our field. This blog post offers a preview.

This is the second blog in our series where we show that our mathematical strengths are an important complement to our programming skills. Using a mathematical approach, we achieve solutions that programming alone couldn't. This time, we speak with Thea, who, along with Bas and then-colleague Alouette, worked on a fantastic project for Boskalis. Their mathematical insights led to a tremendous reduction in computing time, making a previously unusable computation feasible.

Tools like GitHub Copilot, ChatGPT based code assistants, and similar systems have quickly found their way into the daily workflow of software engineers. These assistants represent a significant shift in how we build software. They blend machine learning with long established software engineering practices in a way that is now mature enough for real use in industry.

Complex numerical simulations can be accelerated by training so-called surrogate models using machine learning. Such models give an approximation of the full model but with significantly lower computation times. It enables the use of the model in online control (model-in-the-loop) and allows interactive use and more extensive parameter studies.

Machine learning projects aren't just about developing models. Equally important are the infrastructure and supporting tools that ensure repeatable experiments, well-managed data, and reliable reproduction of results. Based on our experience, we recommend TensorFlow as a framework, MLflow for experiment tracking, and proper data management with DVC (Data Version Control).
