Abstract

The actual formation of glass jars consists of two stages, viz. pressing and blowing. In the first stage the hot (liquid) glass is pressed in a mould to form the 'parison'. The heat transfer in glass and mould can be solved numerically by using a combined BEM/FEM discretisation. In particular, we use a FEM approach for the discretisation of Stokes' equations and the stationary convec- tion diffusion equation in the glass, and a Galerkin BEM approach for the diffusion equation in the mould. This way, one uses the optimal properties of both techniques. The eventual objective is to consider the full nonstationary problem. 1 Introduction The coupling of different numerical techniques has become increasingly pop- ular. When PDEs
