VOF tests

Reconstruction, advection and two-phase flow test cases used for comparison of VOF reconstruction and advection algorithms in A. Esteban et al. "A comparative study of two open-source state-of-the-art geometric VOF methods". Computers and Fluids. <strong>Requirements</strong><br> Tests are performed using OpenFOAM v1812: https://www.openfoam.com/download/release-history.php The algorithms compared in Esteban et al. can be found in the following packages: TwoPhaseFlow gVOF For the generation of non-hexahedral meshes, the following programs are used: tetgen gmsh <strong>Results</strong><br> Results obtained in Esteban et al. for the tests can be found in the <em>results</em> folders, along with the gnuplot scripts <em>.gp</em> to generate the figures.
