Experiments with simple model-order reduction methods

Model-order reduction is a powerful technique to speed up simulations. It can be used to solve performance issues in applications like design optimization, model-based predictive control, or digital twinning. In this blog, we’ll give a very basic introduction to these techniques and describe some experiments that were done at VORtech by two interns at VORtech, Floris Roodenburg and Abinash Mishra. They could speed up calculations by more than a factor of ten.

Team news

There have been many positive developments on the personnel front in the past year. For example, we have welcomed a host of new colleagues and some senior employees are preparing to become partners. We celebrate a series of working jubileesies. We said goodbye to a few colleagues, but that is a natural process in a larger team. Because many of our relations have a personal connection with our colleagues, we thought it good to give an overview of the developments.

Developing an operational information service requires collaboration between operator and scientific software engineer

Building a specialized information system not only requires a developer with domain knowledge, but also a good collaboration between the user and the developer. In this blog, we show how this works in practice, illustrated with examples from a system for monitoring the Dutch coastal waters.

Getting the physics right in simulations

In the simulation of physical processes, some important physical property may get lost due to the computational method. For example, energy loss can be introduced in a simulation of a process that is not supposed to lose energy. Recently, we published new computational methods that avoid such problems. These conservative discretizations conserve certain physical quantities like mass, momentum, and energy. Or all at the same time. This means that our methods make simulations more accurate and more reliable.

Integrating Sphinx in Your CMake Build System

Sphinx is a documentation tool for software projects that can create easily searchable HTML pages and excellent PDFs. It is well suited for documenting scientific code bases due to its support for LaTeX-style equations and numerous extensions for plots, diagrams and much more. It would be nice if we could integrate Sphinx with the common build system CMake so that we can automatically generate documentation. This blog describes an approach to do just that.

25th Anniversary Symposium: “Computer Models in the Workplace: towards Digital Twins and Beyond”

To celebrate our 25th anniversary with our customers, we organize a symposium on Tuesday the 28th of September in the afternoon. The theme will be computer models and algorithms for operational use. We’ll be looking back to where the field came from, but certainly also ahead to what is coming.

The Business Case for Digital Twins

Literally billions of euros in are invested digital twins. Market analysts have reasons to believe that digital twins are really a good investment. Why do they believe that? What is the business case behind all these investments? As a company that provides the technology behind digital twins, VORtech often discusses such questions with our clients. This gives us a good insight in the arguments that are typically made.

Legacy Code: Treasure to Cherish, Pain to Maintain, Part 3

In our practice as scientific software engineers at VORtech, we work for organizations that have computational software as an essential part of their intellectual capital. If successful, a computational software package can exist for many years and even decades. At the same time however, the code base grows and becomes more and more difficult to manage. This is part 3 of a series of blogs in which we discuss how to deal with legacy code.
