FIG. 3.

(Color online) Calculated air–water interface at the critical hydrostatic pressures, over pores with (a) circular, (b) elliptical, (c) triangular, and (d) hexagonal cross-sections. Contour plots show the interface gradient value, . Contour values correspond to 0–0.6. The critical pressure is determined based on the value of .
