From 70096bec800a932019c1eeff50891eb0c062813f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?H=C3=A5kon=20H=C3=A6gland?= Date: Wed, 17 Dec 2025 19:13:58 +0100 Subject: [PATCH] Extend group constraint tests with multi-group hierarchy This commit extends the test_group_higher_constraints test suite with: 1. Extended hierarchy: Added MANI-2 group (with WELL-B) under PLAT to create realistic group competition scenarios where fractions < 1.0. The new hierarchy is: FIELD -> PLAT -> MANI -> WELL-A, WELL-A2 -> MANI-2 -> WELL-B -> PLAT-2 -> WELL-C 2. New tests for getWellGroupTargetProducer(): - TestWellGroupTargetProducerIndividualControl: WELL-A under ORAT - TestWellGroupTargetProducerGrupControl: WELL-A under GRUP - TestWellGroupTargetProducerWithSiblingIndividualControl: WELL-A under GRUP with sibling WELL-A2 under ORAT (demonstrates case where reduction != addback) 3. Updated existing tests: - TestGroupHigherConstraintsWithGuideRate: scale now 0.922 (was 1.39) - TestGroupHigherConstraintsProdWithoutGuideRate: scale now 0.901 --- opm/simulators/wells/BlackoilWellModel.hpp | 18 + tests/GROUP_HIGHER_CONSTRAINTS.DATA | 103 +- tests/test_group_higher_constraints.cpp | 1033 +++++++++++++++----- 3 files changed, 897 insertions(+), 257 deletions(-) diff --git a/opm/simulators/wells/BlackoilWellModel.hpp b/opm/simulators/wells/BlackoilWellModel.hpp index 3296301367..f914b85c5c 100644 --- a/opm/simulators/wells/BlackoilWellModel.hpp +++ b/opm/simulators/wells/BlackoilWellModel.hpp @@ -380,6 +380,24 @@ template class WellContributions; ReservoirCoupling::Proxy& rescoup() { return rescoup_; } const ReservoirCoupling::Proxy& rescoup() const { return rescoup_; } + /// \brief Update guide rates for all wells and groups + /// + /// Computes guide rates based on well potentials and group hierarchy. + /// This is typically called at the beginning of each timestep. + /// + /// \param report_step_idx Current report step index + /// \param sim_time Current simulation time + /// \param deferred_logger Logger for deferred messages + void updateGuideRates(const int report_step_idx, + const double sim_time, + DeferredLogger& deferred_logger) + { + this->guide_rate_handler_.setLogger(&deferred_logger); + this->guide_rate_handler_.updateGuideRates( + report_step_idx, sim_time, this->wellState(), this->groupState() + ); + } + /// @brief Check if this process is a reservoir coupling master bool isReservoirCouplingMaster() const { return rescoup_.isMaster(); } diff --git a/tests/GROUP_HIGHER_CONSTRAINTS.DATA b/tests/GROUP_HIGHER_CONSTRAINTS.DATA index aac49e666f..7072dba57e 100644 --- a/tests/GROUP_HIGHER_CONSTRAINTS.DATA +++ b/tests/GROUP_HIGHER_CONSTRAINTS.DATA @@ -3,24 +3,30 @@ -- individual contents of the database are licensed under the Database Contents -- License: http://opendatacommons.org/licenses/dbcl/1.0/ --- Test case for efficiency factor handling in checkGroupConstraintsProd() +-- Test case for group higher constraints handling in checkGroupConstraintsProd() and getWellGroupTargetProducer() -- Group hierarchy: -- --- FIELD (ORAT = 10000) --- | --- PLAT (GEFAC=0.9, FLD, has GUIDERAT) --- / \ --- / \ --- MANI (GEFAC=0.8) MANI2 (GEFAC=0.7) --- ORAT control FLD control --- | | --- WELL-A WELL-B +-- FIELD (ORAT = 10000) +-- / \ +-- / \ +-- PLAT (GEFAC=0.9) PLAT-2 (GEFAC=0.85) +-- / \ | +-- / \ WELL-C +-- MANI (0.8) MANI-2 (0.75) +-- / \ | +-- WELL-A WELL-A2 WELL-B +-- +-- This setup allows testing: +-- -
