Currently the keyword EQUIL is not supported by the fully
implicit blackoil simulator when using CpGrid. This
commit is a first step towards this as it makes the
implementation of initStateEquil generic.
Note that this patch does not introduce any real temperature
dependence but only changes the APIs for the viscosity and for the
density related methods. Note that I also don't like the fact that
this requires so many changes to so many files, but with the current
design of the property classes I cannot see a way to avoid this...
For constant capillar pressure function the saturation is
determined by cell depths:
Sg_max, Sw_min
----- goc ----
Sg_min, Sw_min
----- woc ----
Sg_min, Sw_max
this basically means using Opm::EclipseState instead of the raw deck
for these keywords.
with this, property modifiers like ADD, MULT, COPY and friends are
supported for at least the PERM* keywords. If additional keywords are
required these can be added relatively easily as well.
no ctest regressions have been observed with this patch on my machine.
the largest change is that all classes below opm/core/props/pvt take
the PVT region index as an argument, the higher-level ones (i.e.,
BlackoilProps*) take cell indices.
Previous fix was wrong because it called getKeyword() outside the
hasKeyword() check. Current version (like original code) uses the
short-circuiting behaviour of && to ensure this.
- Saturations, phase pressures, and standard initialsation of RS and RV
now agree to baseline.
- Tables of RS and RV versus vertical depth (kw RSVD RVVD) have been
hardcoded for testing (need new parser) and the calculations agree to
baseline in the gas and oil zones. In the water zone there is some
differences: Our code computes saturated RS and RV using the final
phase pressures (these are modified to be consistent with saturations
and capillary pressures) while the baseline uses unmodified phase pressures.
It is not quite complete yet for the following reasons:
- it does not compute state.surfacevol(),
- the InitialStateComputer class does not compute Rs or Rv,
- it has not been verified.
