Welcome to VlaPy!

Overview

VlaPy is a 1-spatial-dimension, 1-velocity-dimension, Vlasov-Poisson-Fokker-Planck code written in Python. The Vlasov-Poisson-Fokker-Planck system of equations is commonly used in plasma physics.

Quick Usage

To install dependencies, run python3 setup.py install from the base directory of the repository.

After this step, python3 run_vlapy.py can be executed to run a simulation of Landau damping with collisions.

This will create a temporary directory for the simulation files. Once completed, MLFlow will move the simulation folder into a centralized datastore. This datastore can be accessed through a web-browser based UI provided by leveraging MLFlow.

To start the MLFlow UI server, type mlflow ui into the terminal and then navigate to localhost:5000 in your web browser. The page will look like the following
