Build and test Build documentation PyPI version PyPI versions PyPI license

Installation

pip install open_petro_elastic

Developers and contributors can download the repository and do pip install ".[dev,test,docs]" to install the package with all its dependencies for development, testing, and building the docs.

Usage

The tool can be used as a library, or from the command line using YAML configuration files. For example, see the tutorial config file.

Generally, the open_petro_elastic.material module is used for interfacing with open_petro_elastic as a Python library:

>>> from open_petro_elastic.material import Material
>>> from open_petro_elastic.material.sandstone import hertz_mindlin
>>> mineral = Material(bulk_modulus=1e9, shear_modulus=1e9, density=1000)
>>> sand = hertz_mindlin(mineral, porosity=0.4, pressure=1e6)
>>> print(sand.density)
600.0

To get help on the command line interface:

open_petro_elastic --help

See the docs for more usage instructions.
