# Hybrid Newton Test Suite
This test suite validates the integration of **Hybrid Newton (HyNE)** with machine learning models inside the `flow` reservoir simulator.
It ensures that adding ML-based approximations does not degrade solver performance and, in some cases, improves convergence.
---
## Dependencies
In a similar way as for opm-common ML module, these tests require **TensorFlow** to be installed.
The CPU version is enough for this test and allows faster installation.
```bash
pip install tensorflow-cpu
```
---
## Test Framework
* Implemented with Python’s built-in [`unittest`](https://docs.python.org/3/library/unittest.html).
* Each test case defines a specific **Hybrid Newton configuration** via JSON.
* Simulations are run using `flow`(therefore assuming it is installed):
* **Baseline** → Standard Newton solver (no ML).
* **Hybrid Newton** → Newton solver with ML-based updates injected.
---
## Baseline Simulation
Before running hybrid cases:
* Runs a standard `flow` simulation with the given deck.
* Extracts:
* **Baseline Newton iterations** (`baseline_iters`) from simulation logs.
* **Reservoir state variables** (`PRESSURE`, `SGAS`, `SWAT`, etc.) from UNRST files.
* Stores `n_cells` and `times` for consistency across tests.
---
## Hybrid Newton Simulation
For each test case:
1. A **minimal Keras model** is built that maps input → output features.
* Weights are initialized to copy output variables directly.
* Models are exported using `kerasify.export_model`.
2. A **JSON config** is generated with:
* Input/output features.
* Scaling and feature engineering options.
* Apply time and active cells.
3. `flow` is run with:
```bash
--use-hy-ne=true --hy-ne-config-file=config.json
```
4. Hybrid Newton iteration counts are extracted and compared to baseline.
---
## Assertions
Each test validates:
* **Convergence parity**
Hybrid and baseline must produce the same number of timesteps.
* **Iteration bounds**
`hybrid_iters[t] <= baseline_iters[t]` for all timesteps.
* **Zero Newton cases**
Some cases require the first two timesteps to have `0` Newton iterations.
* **Config integrity**
Config JSONs must exist and be valid.
---
## Test Categories
| Category | Description |
| --------------------------- | ----------------------------------------------------- |
| `ABSOLUTE_CASES` | Tests absolute features. |
| `RELATIVE_CASES` | Tests relative features. |
| `FEATURE_ENGINEERING_CASES` | Tests features engineered inputs/outputs (e.g., log). |
| `SCALING_CASES` | Applies scaling strategies (e.g., min-max, standard). |
| `MULTI_MODEL_CASES` | Combines multiple models into one simulation. |
| `ZERO_NEWTON_CASES` | Use all features, resulting in 0 Newton iterations. |
| `ALL_CASES` | Runs all cases together as a stress test. |
---
## Utilities
The suite uses helper functions from `utils.py`:
* `collect_input_features` → Prepares input arrays from UNRST data.
* `compute_output_vars` → Builds expected outputs from reservoir state.
* `write_config` → Writes the HyNE JSON configuration.
* `export_model` → Saves Keras models in a format usable by `flow`.
* `extract_newtit_from_file` → Extracts iteration counts from solver logs.
* `extract_unrst_variables` → Reads simulation outputs from UNRST files.
