what kind of (structured) grid generator: ellyptic, hyperbolic, algebraic (on what geom. and layout), but i recommend to read Thompson book about this (is freely online avalible from: http://www.hpc.msstate.edu/publications/gridbook/)

- It has some simple example FORTRAN code (appendix C) that guide to resolve your problem.

Gridgen has used a variation of Vinokur's hyperbolic tangent function for distributing points on curves for about 20 years. Marcel Vinokur's original report is a NASA CR (I think).
