OPM Release 2021.10

Dear OPM community,

It is my pleasure to announce that the binary packages for the 2021.10 OPM release are now available for RHEL 7 and 8, as well as for Ubuntu 20.04 LTS (code name Focal Fossa) and Ubuntu 18.04 LTS (code name Bionic Beaver). Note that this is the last OPM release to fully support Ubuntu 18.04  LTS, the next release will instead support 22.04 LTS. The Ubuntu packages may be downloaded from the OPM Project’s Personal Package Archive (ppa:opm/ppa).  If you have not already included this in your package sources, you can do so with the commands

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

Then you can install the simulator and its prerequisites using the command

sudo apt install libopm-simulators-bin

You can install python bindings for opm via pip (https://pypi.org/project/opm/) using

pip install opm

I would also like to use the opportunity to thank all the contributors for their effort in improving the simulator.

Best Regards,
Atgeirr Flø Rasmussen, SINTEF
