also shut unsolvable wells during iterations as default
Note however that getWellConvergence return false if a well is unsolvable
i.e. it will cut the timestep and redo the iteration if the well is unsolvable
and only shut it completly if the time step is below the
MinTimeStepBeforeShuttingProblematicWellsInDays (default 0.01 days)
Assign a maximum ALQ value to each GLIFT producer when doing well testing
in beginTimeStep(). This allows the well to be considered open. Then,
later in the timestep, when assemble() is called, the full gas lift
optimization procedure can adjust the ALQ to its correct value.
It is also observed that in some cases when gas lift is switched off by
setting ALQ to zero, and later in the schedule is switched back on again,
it might not be possible to determine bhp from thp for low small ALQ values.
Instead of aborting the gas lift optimization, we should try increasing
ALQ until we get convergence or until the maximum ALQ for the well is
reached.

If no cell has a valid corner-point geometry, typically caused by

With this commit we instead output a diagnostic message of the form

prevent flow in binary Linux packages from having a timestamp in the
executable that changes with every rebuild.
With the changes in opm-common one can now set the variable
OPM_BINARY_PACKAGE_VERSION to a meaningful version string (Debian
11.2: 2021.10-4). If that is done and flow is built from tarballs it
will now not have a time stamp and print the package version to the
PRT file. E.g.
Flow Version = 2021.10 (Debian 11.2: 2021.10-1)

Renames some methods and variables to reflect that the well is no
longer necessarily a StandardWell. It can be either a MultisegmentWell
or a StandardWell. This should avoid confusion about the nature of
the variable.
If a well is under a group that is limited by a target, it should use as little gaslift as possible.
The reduction algorithm will reduce the gaslift of the well as long as the groups potential is above the groups target.
Introduces two new data types BasicRates and LimitedRates to capture
oil, gas, and water rates, and whether they have been limited by well
or group targets. This reduces the number of variables that are passed
to and returned from various methods and thus makes the code easier to
read.
There was a fallout when skipping concating these files to the
default ones (PR #1708). We should also have deactivated creating
these files at all. As a result these files appeared in all parallel
runs that were aborted.
This change now prevents creating and logging to these files in
parallel in a default
run (--enable-parallel-logging-fallout-warning=false).
Developers can still activate logging and concating to see whether
everything is only logged on the io process by passing
--enable-parallel-logging-fallout-warning=true.
Closes 3725
Introduces a gaslift debugging variable in ALQState in WellState. This
variable will persist between timesteps in contrast to when debugging
variables are defined in GasLiftSingleWell, GasLiftGroupState, or GasLiftStage2.
Currently only an integer variable debug_counter is added to ALQState,
which can be used as follows: First debugging is switched on globally
for BlackOilWellModel, GasLiftSingleWell, GasLiftGroupState, and
GasLiftStage2 by setting glift_debug to a true value in BlackOilWellModelGeneric.
Then, the following debugging code can be added to e.g. one of
GasLiftSingleWell, GasLiftGroupState, or GasLiftStage2 :
auto count = debugUpdateGlobalCounter_();
if (count == some_integer) {
displayDebugMessage_("stop here");
}
Here, the integer "some_integer" is determined typically by looking at
the debugging output of a previous run. This can be done since the
call to debugUpdateGlobalCounter_() will print out the current value
of the counter and then increment the counter by one. And it will be
easy to recognize these values in the debug ouput. If you find a place
in the output that looks suspect, just take a note of the counter
value in the output around that point and insert the value for
"some_integer", then after recompiling the code with the desired value
for "some_integer", it is now easy to set a breakpoint in GDB at the
line
displayDebugMessage_("stop here").
shown in the above snippet. This should improve the ability to quickly
to set a breakpoint in GDB around at a given time and point in the simulation.
This is needed to get consistent estimates for the summary vectors

* {F,G,W}GP{R,T}{F,S} -- Free/Dissolved Gas Production

Refactors getOilRateWithLimit_(), getGasRateWithLimit_(), and
getWaterRateWithLimit_() in GasLiftSingleWellGeneric.cpp. The
common part of the methods is split out into a new method called
getRateWithLimit_(). The purpose of the refactorization is to reduce
reptetive code and make the code easier to maintain.
This is in agreement with C++ Core Guidelines. A member function should
be marked const unless it changes the object’s observable state. This
gives a more precise statement of design intent, better readability, more
errors caught by the compiler, and sometimes more optimization opportunities.
Refactor getOilRateWithGroupLimit_(), getGasRateWithGroupLimit_(),
getWaterRateWithGroupLimit_(), and getLiquidRateWithGroupLimit_() into
a single generic method called getRateWithGroupLimit_().
Consider all groups when reducing oil rate to group limits.
The current code just checks the first group limit in the set.
But there might be groups later in the set with more restrictive
limits, causing the oil rate to be reduced more than the first
limit.
