Adaptive Grid Generation Using Elliptic Generating Equations with Precise Coordinate Controls.

Abstract

The author's results previously reported have now been verified in a double precision code which removes any confusion due to machine round-off error. The results conclusively show no loss of order of accuracy from highly stretched grids, even with stretching parameters in an exponential-of-exponential stretch large enough to increase the size of the error by 6 orders of magnitude.
