  We provide an implementation of the unstructured Finite-Volume Arbitrary
Lagrangian / Eulerian (ALE) Interface-Tracking method for simulating
incompressible, immiscible two-phase flows as an OpenFOAM module. In addition
to interface-tracking capabilities that include tracking of two fluid phases,
an implementation of a Subgrid-Scale (SGS) modeling framework for increased
accuracy when simulating sharp boundary layers is enclosed. The SGS modeling
framework simplifies embedding subgrid-scale profiles into the unstructured
Finite Volume discretization. Our design of the SGS model library significantly
simplifies adding new SGS models and applying SGS modeling to Partial
Differential Equations (PDEs) in OpenFOAM.
