Supplementary Data for: Numerical method for imposing a pinned contact line boundary condition in 2D VOF simulations

Data and Animations to the manuscript: David Gösele, Johannes C. Müller, Jonathan Wurst, Mathis Fricke, Kathrin Schulte "Numerical method for imposing a pinned contact line boundary condition in 2D VOF simulations", referred to as "related publication" in the following: We propose a boundary condition for the volume-of-fluid (VOF) method that uses height functions at the wall to enable contact line pinning. Convergence under mesh refinement of curvature error, spurious currents, and shape error is demonstrated for a static sessile droplet, and close to second-order convergence of the capillary pressure error is obtained for pinning at a sharp edge.

The method is further applied to spontaneous imbibition in a channel with periodic square blocks to investigate capillary pressure barriers in capillary-driven flow. The dataset contains table data to reproduce all shown plots in the related publication, and animations for the figures, where in the related publication, superimposed interfaces are shown.
