Elliptic Grid Generation for Odd Geometries

UPDATED: 08/17/2022

This workbook implements elliptic grid generation for a converging-diverging nozzle. Scrollbars allow the user to input the nozzle contour of their choice. The VBA coding implements a well-established protocol 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.

Grid generated for a symmetric nozzle geometry created using standard elliptic grid generation techniques. The yellow circles indicate points set by the user to define the geometry.
