Computation of properties used in computeConnectionPressureDelta
is factored out to computePropertiesForWellConnectionPressures
The motivation is to be able to use a modified version of
computePropertiesForWellConnectionPressures in the solvent model
The following changes are done in order to remove the duplicated code in
assemble().
- extractWellPerfProperties takes SolutionState as input (only used in
the solvent model)
- the computation of effective parameters is moved to computeAccum()
With these changes the solvent model can use assemble() from the base
model.
The well potentials are caculated based on the well rates and pressure
drawdown at every time step. They are used to calculate default guide
rates used in group controlled wells.
well_perforation_pressure_diffs is stored in
WellStateFullyImplicitBlackoil as it is needed in the well potential
calculations.
- The initial rates are only set to target values for single phase
producers (orat, wrat, grat).
- For injectors compi is used to determine the initial target rates.
Density and viscosity are given as input instead of calculated inside
computeMassFlux. This allow for modifying the properties prior to
calling computeMassFlux which avoids code duplication in the solvent
implementation.
Since PR #541 the arrays cq_s, mob_perfcells, and b_perfcells are
empty if there are no wells in the domain of the process. This
caused segementation faults at various places where we compute
on the wells. With this commit we now guard this places using
asImpl().localWellsActive() and only using the array if the call
returns true.
Also make assemble() more similar to base version, using the
extractWellPerfProperties() member from Base.
To do this it was necessary to change the well_cells member of the
WellOps to be correct for the multi-segment wells (since they may
have different perforation order for some wells).
The convergenceReduction() method no longer takes a number-of-wells argument,
instead it infers the number of well fluxes to check from the size of the
well_flux_eq member of the residual.
After this, a custom getConvergence() method is no longer required for the
multi-segment well model.
This means that details such as calling assemble(), solveJacobianSystem(),
updateState() etc. are now left to the model class. This will make it easier
to create new model classes with different behaviour (such as sequential models).
