this is where the primary solution is stored and is needed for
restart serialization.
this proxies for testing FvBaseDiscretization directly, as
FvBaseDiscretization requires a fully configured simulator to setup.
This commit enables outputting non-linear convergence metrics, i.e.,
the MB and CNV values, per phase, for each non-linear iteration in
each timestep. If the user passes the option value "iterations" to
the --extra-convergence-output command line option, this commit will
create a new output file, CASE.INFOITER, that holds
* report step
* time step within that report step
* elapsed time
* MB and CNV values per phase
* well convergence status
for each non-linear iteration.
We use an asynchronous file writing procedure and confer ownership
of the report step's unprocessed convergence reports to this
procedure just before the end of
SimulatorFullyImplicitBlackoilEbos::runStep()
At that point, the convergence reports are about to go out of scope.
The asynchronous protocol uses a dedicated queue of output requests,
class ConvergenceReportQueue, into which the producer-i.e., member
function runStep()-inserts new convergence reports and from which
the output thread, ConvergenceOutputThread::writeASynchronous(),
retrieves those requests before writing the file data.
This commit introduces a new helper class,
ConvergenceOutputConfiguration
which parses comma separated option strings into a runtime
configuration object for whether to output additional convergence
information and, if so, what information to output.
Supported option string values are
* "none" -- Dont want any additional convergence output.
* "steps" -- Want additional convergence output pertaining to the
converged solution at the end of each timestep.
* "iterations" -- Want additional convergence output pertaining to each
non-linar ieration in each timestep.
Option value "none" overrides all other options. In other words, if the
user requests "none", then there will be no additional convergence
output, even if there are other options in the option string.
We add a new option, ExtraConvergenceOutput (command line option
--extra-convergence-output), which takes a string argument expected
to be a comma separated combination of these options. The default
value is "none". Finally, make the INFOSTEP file output conditional
on the user supplying "steps" as an argument to the new option.
