Welcome to the NUPYCEE website

NUPYCEE is a open-source chemical evolution platform of the NuGrid collaboration. The user can choose between the Stellar Yields for galactic modeling applications (SYGMA) module and the One-zone model for the evolution of galaxies (OMEGA) module.

SYGMA web user interface

The Stellar Yields for galactic modeling applications (SYGMA) module allows to follow the ejecta of of simple stellar populations in a closed-box mode.

We provide an online interface where tables of the evolution of the ejecta of SSP's can be downloaded. Access the interface here. Start the ipython notebook SYGMA.ipynb with a click. Then you can create the SYGMA interface by clicking in the first field and press shift+enter. For a introduction to the interface have a look here.

Notes:

Stellar yields of AGB and massive stars are calculated with the same nuclear physics and are provided by the NuGrid collaboration. The interface is hosted by NuGrid's WENDI platform.

Online User guides

As a introduction to the SYGMA and OMEGA code as well as STELLAB module we provide different interactive online user guides. One can access the web interface here and choose from the following guides:

SYGMA_Userguide
OMEGA_Userguide
STELLAB_Userguide

Within each guide the user can execute commands in the same manner as in in a local downloaded version with a few exceptions.

Download code

All NUPYCEE is publicly available on github. To download the code git is required on your system. First create a directory, for example NUPYCEE, and navigate in it:

           mkdir NuPyCEE
	   cd NuPyCEE

Now download a copy with

	 git clone https://github.com/NuGrid/NuPyCEE.git .

The repository can be found here.

Running SYGMA and OMEGA locally

The ipython environment with numpy and matplotlib are required. A installation of NUPYCEE is not necessary. Instead, you can access the tools through the ipython interactive interface. To run SYGMA and OMEGA have a look at the tutorials in the online documentations (links below) and the DOC directory of NUPYCEE .

The online documentation for SYGMA can be found here and for OMEGA here.

Detailed explanation of physics and input parameter for OMEGA are found on the WENDI platform in OMEGA_Userguide.ipynb here.
