Abstract

The WLSKUM-ED (Weighted Least Squares Kinetic Upwind Method) using the Eigen Directions has shown to be quite robust owing to its ability to work on any point distribution and avoiding the bad connectivity induced code divergence. The weights in the WLSKUM-ED are calculated to diagonalize the least squares matrix such that the multidimensional least squares formulae reduce to the corresponding one dimensional formulae along the eigendirections. This method has been successfully extended to 3-D flow problems and applied to a wide variety of point distributions on various complex bodies ranging from the simplest body of a hemisphere to a multibody configuration of ASLV with strap-on boosters.
