Note 1: The initialization code now always consider 3 phases.
For 2-phase cases a trivial (0) state is returned.
Note 2: The initialization code does not compute a BlackoilStats,
but instead pass the initialization object with the initial state.
The reasoning behind this to make it possible to initialize the case
without SWATINIT in order to compute the same defaulted THPRES values as
Ecl. The initialization needs to be re-computed to account for SWATINIT
in the simulations.
Apply swatInit in the initialization
Stop using the equilGrid in the initialization code
Keep The initialFluidState until end of first time step to make it
possible for flow to output it.
Adds a conservation equation for polymer.
Polymer concentration in the water phase is used as primary variable
The polymer influences the viscosity of the water, and leaves gas and oil
uneffected.
A shear multiplier is computed if PLYSHLOG and/or SHRATE is specified
based on either velocity or shrate.
The shear multiplier effects the water and polymer viscosity.
Tested and verified on the test cases in polymer_test_suite
- initialization only via Ecl Deck
- adds modification of relperms and cap-pressures for miscible runs
- adds TL mixing model for effective viscosity and density calculations
Tested on SPE1CASE2_SOLVENT_MISC_TL, SPE9_CP_CO2_MISC_TL, SPE5CASE1-3
and SPE3CASE1_SOLVENT_MISC
Face centers are computed using the cell corners. With this
implementation the face center seen from a cell may be different from the
face center seen from its neighbour.
Face normals with area lenghts are calculated using the face corners
directly not using a triangulation point in the center of the face.
This gives transmissibility almost equal to eclipse.
