摘要：

Due to the use of the mixed boundary elements in viscous flow computation using the Boundary-Domain Integral Method with the Subdomain Technique the final discretised matrix system is large, sparse and over-determined. The general least squares method for dense matrices demands large memory and CPU resources. As an alternative, an iterative least squares method with diagonal preconditioning is used. The velocity profiles computed with this, FEM and FVM are compared to benchmark valves for a driven cavity Re = 1000.
