Can't you use HyperMorph and create some shape variables? (For OS opt directly or HSt).

In HSt if your node coordinates are your variables, you can just parametrize your .fem file and transform the desired coordinates i. design variables.

There are a few tutorials in HSt help showing how to create a parametrized file (.tpl) and then using it to regenerate your .fem file with the new parameters.

In OptiStruct, just take care with formatting, as it uses 8 character formatting.

Or you can wirte your model using free format:

GRID,1,0.0,10.0,0.5

Then transform it in parametrized file in HSt.
