Abstract
An iterative domain decomposition method is developed to solve 3-D BEM
problems. The method is suited for parallel computation.
1 Introduction
The motivation behind this work lies in conjugate heat transfer modeling of
turbomachinery components using the temperature-forward flux-back (TFFB)
loosely coupled boundary element-finite volume method developed by the
authors[l]. As it is well known, the boundary element method (BEM) only
requires a surface mesh to solve heat conduction problems. However, once
boundary conditions are imposed and the final algebraic system assembled, the
resulting matrix is fully-populated. For large-scale problems, this poses serious
challenges due storage requirements and iterative solution
