  1. Install conda (we recommend mamba)
  2. mamba env create -f env.yaml or mamba env create -f env_gpu.yaml
  3. mamba activate adept

pip

  1. python3 -m venv venv
  2. source venv/bin/activate
  3. pip3 install -r requirements.txt

Examples

There are other ways to use ADEPT, notably as part of a neural network training pipeline that leverages differentiable simulation. In reference [1], neural networks are trained to learn forcing functions that drive the system towards previously unseen behavior. In reference [2], neural networks are trained to help bridge the micro-macro physics gap in multiphysics simulations.

Usage

python3 run.py --cfg {config_path} without the .yaml extension

This runs the simulation defined in the config and stores the output to an mlflow server.

Unless you have separately deployed an mlflow server somewhere, it simply writes files using the mlflow specification to the current working directory.

To access and visualize the results, it is easiest to use the UI from the browser by typing mlflow ui in the command line from the same directory.

The contributing guide is in development but for now, just make an issue / pull request and we can go from there :)
