Description
Solver module to execute the \c functionObjects for a specified solver
The solver specified by either the \c subSolver or if not present the \c
solver entry in the \c controlDict is instantiated to provide the physical
fields needed by the \c functionObjects. The \c functionObjects are then
instantiated from the specifications are read from the \c functions entry in
the \c controlDict and executed in a time-loop also controlled by entries in
\c controlDict and the \c maxDeltaT() returned by the sub-solver.
The fields and other objects registered by the sub-solver are set to
NO_WRITE as they are not changed by the execution of the functionObjects and
should not be written out each write-time. Fields and other objects created
and changed by the execution of the functionObjects are written out.
solvers::functions in conjunction with the scalarTransport functionObject
replaces scalarTransportFoam and provide more general handling of the scalar
diffusivity.
This change means that even if the Courant number is zero, the time step
is adjusted based on maximum time step settings and/or constraints
specified by active fvModels. If none of these additional constraints
are present then adjustment is deactivated.
None of the current thermophysicalTransportModels solve transport equations in
order to evaluate the thermophysical transport properties so it makes more sense
that the evaluation occurs at the beginning of the time-step rather than at the
end where conservative fluxes are available for transport solution. To enable
this the correct() functions have been renamed predict() and called in the
prePredictor() step of foamRun and foamMultiRun and at the beginning of the
time-step in the legacy solvers. A particular advantage of this approach is
that complex data cached in the thermophysicalTransportModels can now be deleted
following mesh topology changes and recreated in the predict() call which is
more efficient than attempting to register and map the data.
An empty correct() function is included in addition to the new predict()
function in thermophysicalTransportModel to support scalar flux transport
closure in the future if needed.
Additionally the two transport model corrector function calls in foamRun and
foamMultiRun have been combined into a single postCorrector() call to allow
greater flexibility in transport property prediction and correction in the
modular solvers.
Given that the number of solid solver modules is currently 1 and unlikely to
exceed 3 it is not very useful to maintain solid and fluid sub-directories and
easier to see the correspondence between the solver modules and tutorial cases
without.
