In this paper we describe a numerical method to simulate particular axisym-
metric viscous sintering problems.
In these problems the material transport
is modelled as a viscous incompressible Newtonian volume flow driven solely
by surface tension.
The numerical simulation is carried out by solving the
governing Stokes equations for a fixed domain through a Boundary Element
The resulting velocity field then determines an approximate
geometry at a next time level by employing a variable step, variable order
Backward Differences Formulae (BDF) method.
This numerical algorithm
is demonstrated for the sintering of two equal spheres.
By sintering is meant the process of bringing a granular compact to a tem-
perature at which the viscosit...
