Schematic of an individual feature. The simulation begins with a small amount of fluid in the region before the feature, with boundaries , , , and , as well as contact lines and positioned at the three phase lines. The feature is of height and width , and the gap is of height .
Time trace of the interface motion through a feature at . Times are denoted for each interfacial position shown.
Time trace of the interface motion for a simulation using dynamic contact angles on the upper surface and at . Times are denoted for each interfacial position shown.
A stretched interface configuration that catches the far corner of the feature.
Result for the GOMA simulations, filled features (large circles) and unfilled features (small circles); curves show results for geometry analysis, both numeric (dashed line) and asymptotic (solid line).
Geometry study based on the assumption of a circular arc-shaped interface, with wetting contact angles on both surfaces.
