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.

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.

Documenting code is something nobody enjoys. But everyone agrees that some documentation is needed. What is the essential documentation and how can documenting be made easier?

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.

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.

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.

Digital twins are the hype of the moment in automation. But the concept is rather ambiguous: people refer to it in many different ways. To bring some order in this confusion, I tried to find a classification of digital twins. It turns out that a single classification is not enough.

At VORtech we mostly work on extending and improving existing code. Let us explain why this is so important and how it works.
