[Opm] OPM 2020.10 Release Available

Wed Nov 18 20:49:47 UTC 2020

Congratulations on the new release of opm flow.  As a user who has
benefited from flow as a tool to teach applied reservoir simulation, it is
gratifying that flow is still being supported. Thanks to your team of
dedicated professionals who believe that open source does not mean
mediocre, lightweight software. Keep up the good work.

> User-Visible Changes and Highlights
> New Command Line Options and Output Files
>
>   *   Add a new output file, CASE.INFOSTEP, that contains per-timestep
> performance numbers (e.g., number of linear solves, number of linear
> iterations, setup time)
>   *   Improve efficiency in loading summary files, especially to support
> manipulating summary data from Python wrappers. This also includes a new
> special purpose utility, called "make_lodsmry", that creates files named
> "CASE.LODSMRY" which contain the summary vectors collected in the time
> direction-all values for one vector before all values of another vector.
>   *   Exclusively use the "flexible" framework for selecting linear
> solvers, through the new command line option "--linsolver". We support the
> preconfigured options "ilu0", "cpr_trueimpes", "cpr_quasiimpes", "cpr"
> (alias for "cpr_trueimpes") or "amg". Advanced users may alternatively
> select a runtime configuration represented in JSON by passing a filename
> with the extension ".json". The default setting is "ilu0".
>   *   Use non-strict tolerances only if a small fraction of the total
> pore-volume violates the strict tolerances. By default the simulator uses a
> non-strict PV threshold of 0.03 (3%), but this is configurable at runtime
> with the new option '--relaxed-max-pv-fraction'.
>   *   Add new option ProjectSaturations (--project-saturations) which

> that use solvents.
> New Simulator Features

>   *   Initial support for calling simulator step functions from Python
> language wrappers.
>   *   Add a new PVT model for CO2 and brine.
>   *   Support salt-dependent water PVT properties.
>   *   Add support for using user-defined arguments (UDAs) in WELTARG and
> GCONPROD requests.
>   *   Add support for using SOF2 (Family II) with Family I (SGOF/SWOF)
> keywords in the case of three-phase solvent models.
>   *   Add support for well-level temperature summary output in thermal
> simulations (keywords WT[PI]CHEA).
>   *   Add support for well, group, and field-level summary output of
> gas-lift injection rates (keywords xGLIR).
>   *   Add summary output for analytical aquifers (AAQR, AAQT, AAQP).
>   *   Support counting abandoned producers/injectors in summary vectors
> [FG]MW[PI]A.
>   *   Implement FILLEPS. Saturation function scaling endpoints also honour
> TOLCRIT when output to the CASE.INIT file.
>   *   Generalise implementation of the FIP keyword and handle summary
> keywords like RPR__REG.
>   *   Improved the error messages from the initial parsing.
>
>   *   Support for group control targets/prediction mode with guide rates.
>      *   Includes voidage replacement and reinjection scenarios.
>      *   Includes support for outputting guiderate values at well and
> group levels to the summary files (summary keywords WxPGR and GxPGR).
>   *   Add more logging for the setup phase when processing the .DATA
> file-including which keywords and their file locations are being processed
> at any one time. This is to assist the user in narrowing down problems in
> the input file.
>   *   Support gas-lift optimisation for standard (non-segmented) wells.
>   *   Add support for editing transmissibility values in the EDIT section.
>   *   Add support for handling MULTZ in a pinched-out column of cells when
> the PINCH multiplier processing mode is 'ALL'.
>   *   Guarantee clean shutdown in a parallel simulation run if any process
> throws an exception.
>
>   *   Add support for running Zoltan-based partitioning on a single
> process only.
> Important Bugfixes

>   *   Fix the default pressure initialization for CT (Carter-Tracey)
> analytical aquifers.

>   *   Fix the way we incorporate gravity terms in boundary conditions
> fluxes.
>   *   Fix bugs with TRAN keywords in EDIT section.
>   *   Ensure VTK dataset filenames use relative paths.
>
>   *   Bugfixes for MPI.
>   *   Fixes to the build, especially for the "opm-upscaling" module.
>   *   Fix a bug in the interaction of TUNING and WSEGITER. This is needed
> for ECLIPSE-compatible restart.
