Simple VOF Solver

Overview

This library numerically simulates the motion of free surfaces and deformable droplets in two- and three-dimensional Cartesian domains using the finite-difference and volume-of-fluid methods. It is built on top of SimpleNSSolver.

Dependency

This solver shares the same dependencies as SimpleNSSolver.

Quick Start

1. Prepare the workspace

   mkdir -p /path/to/your/directory
   cd /path/to/your/directory

2. Clone the repository

   git clone --recurse-submodules https://github.com/NaokiHori/SimpleVOFSolver
   cd SimpleVOFSolver

3. Set initial conditions

   Python3 is used to initialize the flow fields conveniently. You can provide NPY files differently under initial_condition/output/.

   cd initial_condition
   make output
   bash exec.sh
   cd ..

4. Build the solver

   make output
   make all

5. Run the simulation

   bash exec.sh

Documentation

A brief overview of the free-surface treatment is available here. For additional details, please refer to the SimpleNSSolver documentation.

Acknowledgements

The volume-of-fluid method implemented in this solver is based on the THINC/QQ scheme with some modifications.
