Computing curvature for volume of fluid methods using machine learning [PDF]
Journal of Computational Physics, 2019 In spite of considerable progress, computing curvature in Volume of Fluid (VOF) methods continues to be a challenge. The goal is to develop a function or a subroutine that returns the curvature in computational cells containing an interface separating two immiscible fluids, given the volume fraction in the cell and the adjacent cells.
