reticuler 3.3

Simulations of spatial networks growth

Reticuler

Python package to simulate the growth of spatial transport networks in nature.

Documentation

Setup

External dependencies:

FreeFEM++ - PDE solver

Package installation

pip install reticuler

Usage

Four command line scripts are installed during the installation:

• reticulate - runs the simulation
• reticulate_back - runs the the Backward Evolution Algorithm
• clip_ret - clips the network to one of the growth thresholds: maximum forward evolution step, length, height, evolution time, or BEA step
• plot_ret - plots the network based on the .json file from the simulation
• script_ret - prepares a FreeFEM++ script based on the .json file

To use just type in the command line: reticulate -h

Typical network growth simulation:

reticulate -out test --growth_params {\"growth_thresh_type\":1,\"growth_thresh\":2}

• output file: test,
• growth threshold type: maximum network height,
• growth threshold: 2
