Condition improvement for point relaxation in multigrid, subsonic Euler-flow computations:
Abstract: "Insight is given in the conditions of derivative matrices to be inverted in point-relaxation methods for 1-D and 2-D, upwind-discretized Euler equations. Speed regimes are found where ill- conditioning of these matrices occurs, 1-D flow equations appear to be less well conditioned th...

| Zusammenfassung: | Abstract: "Insight is given in the conditions of derivative matrices to be inverted in point-relaxation methods for 1-D and 2-D, upwind-discretized Euler equations. Speed regimes are found where ill- conditioning of these matrices occurs, 1-D flow equations appear to be less well conditioned than 2-D flow equations. Fixes to the ill conditions follow more or less directly, when thinking of adding regularizing matrices to the derivative matrices. A smoothing analysis is made of point Gauss- Seidel relaxation applied to the Euler equations conditioned by such an additive matrix. The conditioned solution method is successfully applied to a very low-subsonic, steady, 2-D stagnation flow." |
