An Analysis of Elliptic Grid Generation Techniques Using an Implicit Euler Solver.

Abstract

Several control function interpolation techniques in a general three-dimensional elliptic grid generation code and their effects on flow solutions using an implicit Euler algorithm are examined. These results will serve to guide the design of control function procedures and interpolation techniques in general grid generation codes. Three configurations and three grid types (O, C, and H grids) are examined. The results indicate that the selection of the control function interpolation techniques, which affect grid spacing, should be based on boundary curvature and spacing. The selection of the interpolation technique can then be made transparent to the user of general grid generation codes. (Author)
