Abstract
The boundary element method is applied to the Stokes problem with a moving boundary in capillary cavities. The numerical method uses a stress/velocity formulation, which is very suitable for the boundary conditions involved. The displacement of the moving surface is calculated explicitly; smoothing and regridding insure stability of the overall scheme. The method allows one to simulate directly the behavior of very thin dynamic films left behind a receding meniscus. The numerical results are compared with both experimental observations and calculations based on a simplified theoretical analysis.
