Data from: A geometric VOF method for interface flow simulations

This set is the original data used in the article titled "A Geometric
VOF Method for Interface Flow Simulations". In this paper, a novel
numerical technique designed for interface flow simulations using the
Volume of Fluid (VOF) method on arbitrary unstructured meshes has been
introduced. The method is called SimPLIC, which seamlessly integrates
Piecewise Linear Interface Calculation (PLIC) and Simpson's rule. The
main focus of the proposed method is to compute the volume of the primary
phase that moves across a mesh face within a single time step. This is
achieved by reconstructing the interface and assessing how the submerged
face area evolves over time. Simpson's rule is employed to integrate
the time evolution of this submerged face area, ensuring an accurate
estimation of the volume of the transported primary phase. The
method's robustness was validated by solving a spherical interface
advection problem in a non-uniform three-dimensional flow across
unstructured meshes with diverse cell types and dimensions. Key metrics
such as volume conservation, shape retention, friction boundedness and
solving efficiency were meticulously monitored and juxtaposed. Numerical
outcomes underscored the precision and adequacy of the PLIC-VOF technique
when complemented with Simpson's rule in advecting the interface.
Furthermore, the SimPLIC method has been integrated into OpenFOAM v2312 as
an unofficial extension and is now accessible to the community.
