FRAGMENT-MNP

FRAGMENT-MNP is a mechanistic model of Micro and NanoPlastic FRAGMentation in the ENvironmenT.

See the full model documentation here.

Usage

FRAGMENT-MNP is in active development at the moment - results should be viewed with caution! That being said, you are welcome to check out the package using the developer instructions below to install it. Also checkout the example usage notebook.

from fragmentmnp import FragmentMNP
from fragmentmnp.examples import minimal_config, minimal_data
import matplotlib.pyplot as plt

# Create the model, pass it config and data, then run it
fmnp = FragmentMNP(minimal_config, minimal_data)
output = fmnp.run()

# Plot the results
plt.plot(output.t, output.n.T)
plt.legend([f'{d} m' for d in fmnp.psd])
plt.show()

Developing FRAGMENT-MNP

We are using Poetry for packaging and dependency management and this is the easiest way to get started. You can install Poetry following these instructions. This presumes you already have Python installed.

After you've installed Poetry, grab a copy of the code from this repo:

$ git clone https://github.com/microplastics-cluster/fragment-mnp.git
$ cd fragment-mnp

Then install the relevant dependencies using Poetry:

$ poetry install 

If you are not already in a virtual environment (i.e. you are not using Conda or virtualenv), this will create a virtual environment in which the package and its dependencies are installed. These instructions detail how you can use this environment. If you are already in a virtual environment, the package and its dependencies will be installed into this.

You can test the installation has worked correctly by running pytest in the project root.

$ pytest
