Abstract

In this paper we describe a numerical method to simulate the deformation of a particular morphology arrising from a mould pressed into the surface of a plate of hot glass. The deformation is driven solely by surface tension. This problem occurs, for example, during the production of cathode ray tubes (CRT). One is typically interested in the relation between the obtained morphology in the finally cooled down glass and the originally pressed morphology by the mould. In this paper a first approach is described to tackle this problem by modelling the fluid as a temperature independent flow. Such a simplified flow can be described by the Stokes equations. The numerical simulation is carried out by solving these Stokes equations for a fixed half space through a Boun
