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

Prepare the workspace

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

Clone the repository

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

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 ..
```
Build the solver
```
make output
make all
```
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.
