    Merry Christmas and Happy 2021

    It has been a difficult year for many of us: some had to face illness and some are not among us anymore, others suffered losses, and many are struggling while they try managing a situation we imagined possible but were hardly unprepared to live. In times like these, spending time with the people we love matters even more than usual. Particularly for our elderly, who are more isolated due to the restrictions imposed by the pandemic, which keep them safe but also make them feel lonelier.

    Contributing research work to open-source projects

    As the main developer of OpenQBMM, an add-on for OpenFOAM which implements quadrature-based moment methods for the solution of generalized population balance equations, I have been recently involved in the transfer of the copyright on the OpenQBMM code base to the OpenFOAM Foundation, to be able to contribute the corresponding source code to them. I summarize here some motivations, lessons learned and some advice that may be useful to others who want to follow the same path. Why contribute? This is a question several have asked. Why contribute a code base that took four years of work to be build (and quite some nights, holiday, weekends too), including research, overcoming…
