Computational science and engineering parameteric study workflows

Description

WAVES (LANL code C23004) is a computational science and engineering workflow tool that integrates parametric studies with traditional software build systems.

In addition to the parametric study Python package and command line utilities, WAVES also includes SCons builders for common engineering software used by model simulation (modsim) repositories. The tutorial simulations in this project use SCons as the automated build system and translate software build system concepts in the language of engineering simulation and analysis. The SCons documentation should be consulted as a reference for additional build system concepts, command line options, and project configuration.

This project includes a MODSIM-TEMPLATE which is used for the tutorials and for integration and regression testing of the WAVES extensions to SCons. The template modsim project can be duplicated from the command line as waves fetch modsim_template after installation.

Installation

Conda

WAVES can be installed in a Conda environment with the Conda package manager. See the Conda installation and Conda environment management documentation for more details about using Conda.

$ conda install --channel conda-forge waves

pip

WAVES may also be installed from PyPI with pip under the distribution name waves-workflows: https://pypi.org/project/waves-workflows/. The package installs and imports as waves, so care must be taken to avoid name clashes with similarly named PyPI packages.

$ pip install waves-workflows

Spack

WAVES may be installed with the Spack package manager under the distribution name py-waves: https://packages.spack.io/package.html?name=py-waves. The package installs and imports as waves.

$ spack install py-waves

Documentation

The documentation is bundled with the Conda package and can be accessed locally without a network connection after installation from the command line as waves docs. The documentation is also web-hosted:

• GitHub: https://lanl-aea.github.io/waves/index.html

• LANL: https://aea.re-pages.lanl.gov/python-projects/waves/

The MODSIM-TEMPLATE documentation is hosted as a separate webpage as a demonstration for what modsim project documentation can look like.

  $ git clone [e-mail]:lanl-aea/waves.git

• LANL

  $ git clone ssh://[e-mail]:10022/aea/python-projects/waves.git

Local development environments

SCons can be installed in a Conda environment with the Conda package manager. See the Conda installation and Conda environment management documentation for more details about using Conda.

1. Create the environment if it doesn’t exist

   $ pwd
   path/to/local/git/clone/waves
   $ conda env create --name waves-env --file environment.yml

2. Activate the environment

   $ conda activate waves-env

In addition to the primary development environment file environment.yml, several other environment files are maintained for CI jobs. For Windows developers, environment-win.yml removes packages that are not available for Windows and packages that are only necessary for deployment jobs. The conda-build.yml and pip-build.yml are stripped down to the bare essentials for building Conda and pip packages, respectively.

Documentation

The documentation build is automated with SCons as the documentation target. The HTML documentation builds to waves/build/docs/html/index.html
