Abstract

This paper presents a Boundary Element Method (BEM) formulation for the three-dimensional steady-state convection-conduction problems and a BEM sensitivity formulation for the determination of sensitivities of temperature and heat flux to a boundary shape parameter. The BEM sensitivity formulation is based on the direct differentiation approach (ADD). These formulations are applied to simulate deep penetration laser welding. It is found that the BEM and sensitivity formulations are very efficient and robust in the determination of the solid-liquid interface in a workpiece.
