NuPyCEE

Public NuGrid Python Chemical Evolution Environment

This is a code repository containing the simple stellar population code SYGMA (Stellar Yields for Galactic Modeling Applications), the single-zone galaxy code OMEGA (One-zone Model for the Evolution of Galaxies), and the observational data plotting tool STELLAB (Stellar Abundances).

Requirement: The codes are now in Python3 and use the "future" module.

Online usage: These tools can be used directly online via the public WENDI interface.

Userguides: See the Documentation folder.

Acknowledgments:

• SYGMA: Please refer to Ritter et al. (2017).

• OMEGA: Please refer to Côté et al. (2017).

• STELLAB: Please refer to the NuPyCEE code library.

Installation Instructions

• Create the directory where you want to download the codes.
• Go in that directory with a terminal and clone the GitHub repository:
  • git clone https://github.com/NuGrid/NuPyCEE.git
• From the same directory which contains the cloned NuPyCEE directory, you can import the codes in Python mode by typing:
  • from NuPyCEE import omega
  • from NuPyCEE import sygma
  • from NuPyCEE import stellab
• If you want to import the NuPyCEE codes from anywhere else within your work space, you have to update your Python path using a terminal:
  • export PYTHONPATH="your_path_to_before_NuPyCEE:$PYTHONPATH"
  • Example: export PYTHONPATH="benoitcote/gce_code:$PYTHONPATH"
  • Important: Do not forget :$PYTHONPATH at the end, otherwise the python path will be overwritten.
  • Note: All export commands should be put into your bash file. With MAC, it is the .bash_profile file in your home directory. Otherwise, you will need to define the paths each time you open a terminal.

Installation of the Decay Module for Using Radioactive Isotopes

• In the NuPyCEE folder, type the following
  • f2py -c decay_module.f95 -m decay_module
  • Note: Use the f2py version that will be compatible with your Python version.
