In this paper it is shown that the current methods of graph representation
used for finite-element mesh partitioning are inappropriate for tall buildi
ngs, where the mesh will generally consist of both one and two dimensional
elements. A new graph representation, called the bubble graph, is proposed
and the results of decomposing these graphs using standard graph partitioni
ng tools are presented. The new graph representation is shown to be appropr
iate for the partitioning of finite-element meshes of tall buildings.
