OPM release 2019.04

Dear OPM community!

We are happy to announce the 2019.04 release. Binary packages are available for Ubuntu Linux 16.04, 18.04 and 18.10 as well as Red Hat Enterprise 6 and 7.

As for the last release, we have been forced to disable MPI for the Ubuntu 18.04 package. If you want to run Flow in parallel you must use another version of Ubuntu, or compile it yourself.

The release manager for this release was Arne Morten Kvarving.

OPM summit 2019 in Utrecht

Dear OPM community,

We would like to invite you to participate in the 2019 OPM Summit on January  24th and 25th  in The Netherlands! This year the event will be hosted by TNO and we hope to welcome all of you in Utrecht. The details of the event are as follows:

*   Location:            Princetonlaan 6, Utrecht, The Netherlands
*   Dates/Time:      24th and 25th of January 2019. Start: 10:00 on Thursday and end at 15:00 on Friday
*   Fees:                   There are no fees for the meeting, Conference facilities and food will be provided by TNO

Please let me, Rohith Nair (rohith.nair@tno.nl), or Frank Wilschut (frank.wilschut@tno.nl) know as early as possible if you are planning to join the summit, so that we can make the necessary arrangements. We plan to make Thursday (24th) more user centered and Friday (25th) more developer focused, however the agenda is flexible and you can participate on either or both days. The agenda and the presentation slots for the meeting are still open so you are welcome to propose items you would like to share with the rest of the OPM community. If you would like to make a presentation please make the same request to the organizers with a title, authors and a paragraph describing the talk, preferably before 15 January. The agenda will be published on the website and to the participants as soon as it has been set. There will also be a conference dinner on the evening of the 24th (Thursday); in your reply please indicate if you would like to join the dinner.

Travel/Accommodation: Participants must make their own arrangements. Our office is on the university campus, but we recommend hotels in the city center or near the central train station (e.g. the NH and Apollo hotels). From the city center, TNO is easily accessible by bus or taxi.

Looking forward to seeing you here!
The Organizers (Rohith Nair and Frank Wilschut)

Updated Flow manual available

An up-to-date reference manual for OPM Flow is now available. The manual describes the structure and keywords of the input deck format, installation, how to run Flow, and command line parameters. All implemented functionality to date is included. We hope that it will be useful!

We would like to thank David Baxendale in particular for his hard work on the manual!

2018.10 release of OPM

Dear OPM community,

we are happy to announce the 2018.10 release. Binary packages for Red-Hat Enterprise Linux 6 and 7 and Ubuntu 16.04 and 18.04 are available for download.

In addition to the usual list of fixes and improvements two significant improvements include:

  1. flow can now write restart files which can be used to restart eclipse.
  2. Performance has been improved significantly, on selected field models flow is significantly faster than eclipse.

Due to problems with the Zoltan package we have unfortunately been forced to disable MPI for the Ubuntu 18.04 package. We are looking into this, and if possible we will make updated packages at a later stage.


OPM release 2018.04

Dear OPM community,

I am happy to announce the 2018.04 release. Packages for Ubuntu 16.04 and Red-Hat Enterprise Linux 6 and 7 is prepared. New in this release is that also the Red-Hat packages are shipped with mpi support.

In addition to various minor bug-fixes and a reorganization of the code, the release contains new functionality for the Flow simulator like DRSDT support, experimental CPR preconditioning and enhanced output capability. Note that number of modules are reduced to simplify the build process and the code maintenance. The new module organization is shown here.

Module reorganization

Major reorganization of opm modules have taken place in preparation for the next release:

  • The opm-core module has been removed, its contents moved to appropriate locations in other modules.
  • The opm-parser and opm-output modules have been folded into the opm-common module. If you do not need these features, there are build-system options for opm-common that allow you to build without them: set ENABLE_ECL_INPUT to false to not build the Eclipse deck parser feature, and/or set ENABLE_ECL_OUTPUT to false to not build the Eclipse binary I/O feature. Both of these default to true, and setting them to false will disable building some downstream programs such as Flow.

The new structure is shown on the module page.
