    A basic geometry module

    It is time for another update about my hobby project. I have been working on a module to perform basic operations on the geometry used to perform CFD simulations. Originally my application did this inside the module used to configure meshing with snappyHexMesh. However, this directly linked the geometry assembly to the mesh. I wanted to separate the two tasks for two reasons: Allow the same geometry assembly to be reused in multiple simulations. This also allows to reduce the number of times the same geometry information is stored, which is good side effect. Reduce the complexity of the mesh configuration tool. Focus of this update is the part of…

    Bye bye social media. For good, this time.

    Some time ago, I took a break from social media and then gave them another try. Today I deleted my account on the only generalist social medium I have consistently used. Social media have proven to be excessively powerful tools, out of the control of governments, institutions, people who use them. They have not been sufficiently regulated, have dodged rules some governments have long tried to impose on them, and have become, also thanks to their slow response and inaction, a mean of dissemination of ideas that are far from positive and constructive, as recent events have shown, not for the first time. It has been interesting to request my…

    Some updates on my hobby project

    Some time ago I tweeted about working on a web-based UI for our codes (and snappyHexMesh) to facilitate working with students and also to make the process less tedious for me, which does not hurt. I have never done development with web technologies until two years ago: most of my focus has been on implementing numerical algorithms. I have written UI code in the past using GTK and Qt, but I was quite far from anything web-related, aside from basic HTML. Saying the learning curve was steep is an understatement, but with the help of a very good friend (with the patience of a saint 😀 ) I have slowly…

    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. Call them, particularly in these days, when loneliness hits them harder. Take time to do it often and don’t rush your calls. It does…
