With this we announce the availability of the 2024.10 OPM Flow release. Binary packages are available in OPM’s PPA (personal package archives), ppa:opm/ppa. If you have not already enabled this PPA in your package sources you can do so through the following two commands:

sudo add-apt-repository ppa:opm/ppa
sudo apt update

The 2024.10 OPM Flow release supports the following two Ubuntu LTS versions

• 22.04 LTS (codename Jammy Jellyfish)
• 24.04 LTS (codename Noble Numbat)

Binary packages are also available for RHEL 8 thanks to Arne Morten Kvarving. This is greatly appreciated. If you wish to build the release manually on your own system you can check out the release/2024.10 branch at tag release/2024.10/final.

This release has seen work in many areas, but the most visible change to users is the addition of several new summary vectors to help analyse CO2 storage processes. These were largely motivated by the 11th SPE Comparative Solutions Project which studies such processes at both lab and field scale. I would also like to thank the accelerator/GPU developers for their contributions to making this release more amenable to such hardware. More such work is expected in future releases. There has also been a lot of effort put into improving the default settings for the simulator’s linear and non-linear solvers as well as improvements to the non-linear domain decomposition method.

Some additional highlights of the release are

• Support for the ‘ALL’ flag in item 4 of PINCH
• Support for parallel partitioning using the METIS software in addition to the existing Zoltan package
• Proper handling of the WHISTCTL in restarted simulations

Further highlights and more complete changelogs are in the GitHub release pages for this release

Thank you, again, to all who contributed to this release. Users who reported issues, developers who added new features, performance improvements and provided fixes to issues. Finally, a special gratitude to Markus Blatt and Arne Morten Kvarving for creating the binary packages.

It is my hope that this release will be useful to users. Do please continue to report problems if you find any.
