Galactic Chemical Evolution Integrator
Project description
VICE: Versatile Integrator for Chemical Evolution
77 elements on the periodic table
Fast integration of one-zone models
Enrichment from single stellar populations
Highly flexible nucleosynthetic yield calculations
- User-defined mathematical forms describing:
Nucleosynthetic yields in simulations
Mixing processes in multi-zone models
Infall and star formation histories
The stellar initial mass function
The star formation law
Element-by-element infall metallicities
Type Ia supernova delay-time distributions
How to Access the Documentation:
Documentation is available in several forms:
Online: http://vice-astro.readthedocs.io
In PDF format, available for download at the same address
In the docstrings embedded within the software
Running vice --docs from the terminal will open the online documentation in the default web browser.
First time users should go through VICE’s QuickStartTutorial jupyter notebook, available under examples/ in the git repository. This can be launched from the command line by running vice --tutorial. Other example scripts can be found there as well.
