@menno received a post-doc fellowship from CIG (geodynamics.org) to greatly improve the world builder in the coming months. Thanks to CIG and all the collaborators of the project, and I am sure we are going to make great progress in the next few months!

A small but important change for all world builder input files using mid oceanic ridges.

The development release now allows defining multiple ridges per feature. This does mean that input files using ridges will need to be updated to include an array around the ridge coordinates. So [[1,2],[3,4]] becomes [[[1,2],[3,4]]].

This also means that you now can define multiple ridges as [[[10,20],[20,30],[10,40]],[[50,10],[60,10]]]. For more info see: github.com/GeodynamicWorldBuil

The world builder has changed the name of the main branch from `master` to `main`.

If you are new to the world builder, you don't need to worry about this and you can just clone the repository as usual. If you already have a local cloned repository, github should show instructions on how to update your repository, or you can take a look here: github.com/GeodynamicWorldBuil for instructions and more information.

My (open access) paper on modelling Crystal Preferred Orientation (CPO) in geodynamic models with Magali Billen is now published and is available here: dx.doi.org/10.1029/2021GC00984 . It implements and explorers the use of CPO modelling to better constrain future geodynamic models!

The work was performed with all open source research code: ASPECT (aspect.geodynamics.org), The Geodynamic World Builder (@world_builder, geodynamicworldbuilder.github.) and the CPO analyzer (github.com/MFraters/cpo_analyz)

Progress has been made in recent weeks. A major highlight is the addition of the mass conservative slab temperature model together with the half space cooling temperature model for the oceanic plate by Magali Billen. Another highlight is fixing slabs and faults beyond the -180 and 180 range.

A big change which I am now working on is defining the radius in spherical coordinates while keeping ensuring consistency between the world builder and the calling program (see github.com/GeodynamicWorldBuil).

I am happy to announce the release of version 0.4.0 (Cascadia) of the Geodynamic World Builder. Besides a lot of other things (see the changelog), the most notable new features of this release is the new continuous slab. This allows for much more smooth and realistic slabs to be made.

The code name Cascadia comes from the Cascadia subduction zone. Find out more at github.com/GeodynamicWorldBuil Enjoy!

The movies showing models of Crystal Preferred Orientation (CPO) development in a 3D subduction zone and a ridge model from my submitted paper can be found on tube.mfraters.net/video-channe. The submitted paper itself is available on a preprint sever: doi.org/10.1002/essoar.10506908.1.

I recently wrote a blog post for the EGU geodynamics blog about trying out new program languages for your research. I hope I can convince you to try at least one of them: blogs.egu.eu/divisions/gd/2021

The world builder website (geodynamicworldbuilder.github.) has been updated to include the post of this Mastodon account! This will make it easier to post updates and allow the website to stay up to date with the development 🎉


This is a personal Mastodon instance where will mostly post about science and programming. If you are interested in a personal or project account on this server, feel free to contact me.
