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.

OPM release 2017.10, update 1

Dear OPM community,

We have created an update for the 2017.10 release. It fixes a few bugs in Flow that could affect simulation results slightly and also lead to very bad performance when running Flow in parallel using MPI. The effect was most pronounced when running with more than 4 MPI processes.

Binary packages for Ubuntu 16.04 and Red Hat Enterprise Linux 6 and 7 have been updated, and for most users your systems will ask to install the updated version or do it automatically.

For those who compile OPM from source, the release branches on GitHub have been updated and tagged with

release/2017.10/update1

The master branch of course includes the same fixes.

OPM release 2017.10

Hi,

On behalf of the OPM project, I’m happy to announce that version 2017.10 has been released. Packages for Ubuntu 16.04 and Red-Hat Enterprise Linux 6 and 7 have been prepared or should be available soon.

As usual, this release contains a multitude of new features and improvements. Most notable are probably that the Flow simulator is now considerably faster than in the 2017.04 release, Flow now supports the solvent and polymer black-oil extensions and that there now is freely available documentation for the file format that is used to specify the input.

Finally, as the release manager, I’d take the opportunity and thank everyone involved in making the release process for 2017.10 go as smoothly as it did.

Have A Lot Of Fun!

Andreas
