About The Project

This repository was originally designed to solve the problem of complex OpenFOAM case structure, and the solution was to re-present the original cases using the common configuration file format YAML. Later, since there is a corresponding package for the YAML format in Python, I wrote this Python interface package for OpenFOAM, and then I added progress bars to most OpenFOAM solvers by analyzing log files in real time. Although there are still many details to be specified in this repository, its function of generating cases and calling solvers is ready for preliminary use, for example, I used this package to generate cases in batch in my own project. In the future I would like to integrate the post-processing steps into this interface package as well.

Getting Started

To get a local copy up and running follow these simple example steps.

Prerequisites

This project currently uses Poetry to manage Python dependencies. I've heard good things about PDM so far, and may provide PDM support subsequently. If Poetry is not installed, you can refer to official installation guide.

Installation

1. Clone the repository

   git clone https://github.com/iydon/of.yaml.git
   

2. Install Python dependencies

   poetry install --extras full
   

3. Activate the virtual environment

   poetry shell
   

4. (Optional) Convert Python package into a single file

   make standalone

Usage

Demo

Save the following demo code as a separate file (e.g. demo.py).

from foam import Foam

foam = Foam.from_file('tutorials/incompressible/simpleFoam/airFoil2D.yaml')
foam.save('airFoil2D')
foam.cmd.all_run()

Running the demo code in the virtual environment results in the following output.

$ poetry run python demo.py
Running simpleFoam on .../of.yaml/airFoil2D

Tutorials

The following table shows the OpenFOAM cases that have been converted to YAML format. You can find the corresponding rules by comparing the YAML format with its original format, and I don't have the time or interest to organize the corresponding documentation for the time being.

Task List

The following is a task list to convert OpenFOAM-7 to the corresponding YAML format. The corresponding rules for conversion are not currently organized because some of them are still unstable. I will first try to convert as many tutorials as possible, and then organize the rules afterwards.
