Best way to do sensitivity analysis

[robo1billion]

Does anyone here have a recommended way to do manual sensitivity analyses. I had been using the
*create
*end
*use
in conjunction with the built in optimisation functionality (/opt). However, I found even when using the zero order optimisation option that my results are very dependent on my initial design.

Is it possible to place *create, *end, *use in a DO loop and maybe read in geometric values from a text or excel file?

Any recommendations would be appreciated.
