since the unit code within opm-parser is now a drop-in replacement,
this simplifies things and make them less error-prone.
unfortunately, this requires quite a few PRs. (most are pretty
trivial, though.)
Upstream (opm-parser) now provides a better Equil + EquilRecord, and
simultaneously deprecated EquilWrapper. This patch fixes the resulting
breakage.
One important note: The new Equil does not expose integers for live
oil/wet gas initialization procedure methods, but rather booleans
through constRs/constRv methods. This is how the variable behaves
according to the Eclipse reference manual (EQUIL keyword section).
Code has been updated to reflect this.
This commit introduces a new public method, activeRegions(), that
retrieves those region IDs that contain at least one active cell.
We furthermore extend the cells() method to support lookup of
arbitrary region IDs. Non-active region IDs produce empty cell
ranges.
Intended use case is
for (const auto& reg : rmap.activeRegions()) {
const auto& c = rmap.cells(reg);
// use c
}
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.
In summary:
- added RsFunction (base class),
- made NoMixing, RsVD, RsSatAtContact inherit RsFunction,
- RS and RV are no longer template arguments for EquilReg class,
- EquilReg constructor now takes two shared_ptr<Miscibility::RsFunction>,
- use of constructor updated, mostly using make_shared.
This commit adds support for assigning the initial phase pressure
distribution to a subset of the total grid cells. This is needed in
order to fully support equilibration regions. The existing region
support (template parameter 'Region' in function 'phasePressures()')
was only used/needed to define PVT property (specifically, the fluid
phase density) calculator pertaining to a particular equilibration
region.
This commit adds a simple facility for calculating initial phase
pressures assuming stationary conditions, a known reference pressure
in the oil zone as well as the depth and capillary pressures at the
water-oil and gas-oil contacts.
Function 'Opm::equil::phasePressures()' uses a simple ODE/IVP-based
approach, solved using the traditional RK4 method with constant step
sizes, to derive the required pressure values. Specifically, we
solve the ODE
dp/dz = rho(z,p) * g
with 'z' represening depth, 'p' being a phase pressure and 'rho' the
associate phase density. Finally, 'g' is the acceleration of
gravity. We assume that we can calculate phase densities, e.g.,
from table look-up. This assumption holds in the case of an ECLIPSE
input deck.
Using RK4 with constant step sizes is a limitation of this
implementation. This, basically, assumes that the phase densities
varies only smoothly with depth and pressure (at reservoir
conditions).
