✦ Synopsis
An interface element to model the pressure discontinuity due to surface tension when applied to the ®lling of a thin section cavity is presented. The equations used to form the element matrix for the interface element are the line integral form of the continuity and momentum equations. During the development of the ®nite element model, the pressure dierence across the free surface due to surface tension is treated as an additional traction and is applied to all element sides which form the free surface. Simple numerical examples are then presented to illustrate the technique on the ®lling of a rectangular thin section cavity.
