Simple VOF Solver

_ _ _ _

Overview

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

Dependency

Same dependency as the SimpleNSSolver.

Quick start

1. Prepare workplace

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

2. Get source

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

3. Set initial condition

   Here Python3 is used to initialise the flow fields conveniently. One can give NPY files in different way under initial_condition/output/.

   cd initial_condition
   make output
   bash exec.sh
   cd ..

4. Build solver

   make output
   make all

5. Run

   bash exec.sh

Documentation

Free-surface treatment is briefly documented here. Please refer to the documentation of SimpleNSSolver for other details.

Acknowledgements

The volume-of-fluid method is based on THINC/QQ scheme with some modifications.
