A flexible Chemical Evolution model in python

Documentation

For the latest documenation please see here.

Python Versions and Dependencies

• Python 2.7 or 3.3+
• numpy
• scipy
• matplotlib
• pandas
• seaborn

Installation

Choose a location for flexCE to live. We'll assume that it's in your home directory ("~/").

cd ~/flexCE
 python setup.py install

Generate yields:

cd ~/flexCE/flexCE/
 python make_yield_grids.py

Run the code

cd ~/flexCE/flexCE/
 python flexce.py ../config/sim0.cfg

Change the parameters of the code:

1. create a new simN.cfg file (where N is a number)

2. edit simN.cfg

3. re-run the code:

   python flexce.py ../config/simN.cfg
   

Plot [O/Fe]-[Fe/H]:

cd flexCE/flexCE/plot
 python plot_xfe_feh.py ofe_feh_sim0.cfg

Go to output plot directory:

cd flexCE/plots/plots
