stelladb 0.2.11

Includes functions to upload DESC and VMEC data to the stellarator database.

Stellarator-Database

Includes the functions required to upload DESC or VMEC results to the stellarator database. You can access the database here.

This is still a work in progress.

Install using pip

If you are on Linux, WSL or MacOS, you should be able to install stelladb directly from PyPi.

pip install stelladb

You may have difficulty installing on Windows due to simsopt dependency. More detailed instructions will come for that. For now, you can use the repo on Windows with slight difference on building the environment.

Install using GIT

Clone GIT repo

git clone https://github.com/PlasmaControl/Stellarator-Database.git

Once you get the files,

cd Stellarator-Database

Building conda environment

conda create --name db 'python>=3.9, <=3.12'
conda activate db
pip install -r requirements.txt

If you are on Windows, simsopt might need additional instructions. If you just want to upload DESC results, follow these steps for creating conda environment,

conda create --name db 'python>=3.9, <=3.12'
conda activate db
pip install desc-opt selenium

Then, you can upload to database inside the repo, or anywhere where you can access the module stelladb. You can either git clone the whole repository or you can just get the stelladb folder of the repo and copy it to where you want to call the functions from.

Sample usage

For more detailed explanation, refer to the tutorial.ipynb notebook in the repo.

from desc.examples import get
from stelladb import save_to_db_desc

eq = get("HELIOTRON")

# if you are using DESC, you can directly upload Equilibrium or 
# EquilibriumFamily objects. For EquilibriumFamily, only the last
# Equilibrium will be uploaded.
save_to_db_desc(eq, config_name="test-HELIOTRON", user="username")

# if you have an outfile, supply the name of it without extension
# For DESC example, we need to save it first to get the .h5 file
eq.save("test_output_HELIOTRON.h5")
save_to_db_desc("test_output_HELIOTRON", config_name="another-HELIOTRON", user="username")

# use copy parameter, if you want the local copy of the files that are uploaded
# default value is False
save_to_db_desc(eq, config_name="HELIOTRON-test-name", user="username", copy=True)

You can give config_name as you wish. However, if there is an existing configuration with same parameters in the database, you will get following error,

Configuration data already exists in the database with name: HELIOTRON.

Then, you should change your config_name to match that and try again.

VMEC Utilities are not tested yet!
