FIG. 1.

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 .

FIG. 3.

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.

Image of FIG. 4.
FIG. 4.

A stretched interface configuration that catches the far corner of the feature.

Image of FIG. 5.
FIG. 5.

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).

Image of FIG. 6.
FIG. 6.

Geometry study based on the assumption of a circular arc-shaped interface, with wetting contact angles on both surfaces.
