Fastener builder utility application on composite.

[salvenheit]

Hello,

I would really appreciate if you could tell me how to improve the Patran utility application "Fastener builder" so it calculates the in plane cbushes spring constants (translational and rotational) different when created on orthotropic composite laminates (with different E11 and E22).
Can the application code be improved?

Thank you very much in advance,

Salva.
