Excel/VBA Spreadsheet for Elliptic Grid Generation
Grid Generation (Updated: 3/25/2010)
This workbook
implements elliptic grid generation for a converging-diverging nozzle. Scrollbars allow the user to input the
nozzle contour of his or her choice.
The VBA coding implements a well-known scheme for elliptic grid
generation. The user can select
either a pair of Laplace or Poisson equations. In the latter case there is some control
given over the magnitude of the Poisson terms, which may be used to attract or
repel grid lines from the boundaries and to affect the angles at which lines
intersect the boundaries. The case
seen in the figure uses both.
