# PorousMediaLab

The toolbox for batch and 1D reactive transport modelling in porous media aimed at the easiness of use for the user without computational background.

## What's New in v2.1.1

**Correctness and packaging hardening** for solver setup and release artifacts:

- Validates time and spatial grids to prevent silently shifted `dt` and `dx`
- Fixes ODE derivative ordering, `Batch` solver dispatch, flux estimators, and calibration depth comparisons
- Removes obsolete binary build artifacts and legacy upload scripts from the source distribution

## What's New in v2.1.0

**2.4x overall performance improvement** with optimized rate reconstruction:

- Vectorized `reconstruct_rates()` method - 45x faster
- Enabled numexpr multi-threading for parallel rate expression evaluation
- Pre-allocated arrays in hot loops to reduce memory overhead

## What's New in v2.0.0

**6-60x faster reaction integration** with the new vectorized ODE solver:

- Reactions are now solved using a vectorized approach that processes all spatial points simultaneously
- Uses `scipy.integrate.solve_ivp` with LSODA method (auto-detects stiffness)
- Backward compatible: use `ode_method='scipy_sequential'` for the old behavior

| Spatial Points | Species | Speedup |
|----------------|---------|---------|
| 50 | 2 | 13x |
| 100 | 3 | 23x |
| 500 | 5 | 62x |

# How to use

Have a look at ["examples"](https://github.com/biogeochemistry/PorousMediaLab/tree/master/examples) folder.

# Installation using pip

- Install Python version 3.10 or higher ([click](https://www.python.org/downloads/));
- To install the toolbox run ```pip install porousmedialab```
- In terminal run ```jupyter notebook```;
- You will see the folders in your home folder. You can navigate in any folder and create a new notebook with your model.

# Development installation using Poetry

- Install Python version 3.10 or higher ([click](https://www.python.org/downloads/));
- Install Poetry ([click](https://python-poetry.org/docs/#installation));
- Clone this repository: ```git clone https://github.com/biogeochemistry/PorousMediaLab```
- Navigate to the project folder: ```cd PorousMediaLab```
- Install dependencies: ```poetry install```
- Run tests: ```poetry run pytest```
- Activate the virtual environment: ```poetry shell```

## Development Commands (Makefile)

The project includes a Makefile for common tasks:

```bash
make install       # Install dependencies

make build         # Build package
make publish       # Publish to PyPI
make release       # Build and publish
make clean         # Clean build artifacts
```

# Manual installation

- Install Python version 3.10 or higher ([click](https://www.python.org/downloads/));
- Download and unzip or clone (using git) this repository (PorousMediaLab);
- Open terminal and go to the PorousMediaLab folder using ```cd``` command. If you have problems with the terminal, check this [guide](https://www.davidbaumgold.com/tutorials/command-line/);
- Install dependencies: ```pip install numpy numexpr scipy matplotlib seaborn h5py scikit-learn```
- In terminal run command ```jupyter notebook```;
- You will see the folders of the PorousMediaLab project; you can go in "examples" folder and play with them.

# Testing

To run the test suite:
