Hi,

I am reducing the weight of a wingbox which consists of laminate plates. To implement a proper optimization scheme, I need to know how to change laminate stiffness matrices A and D. In Ansys ADPL language, I could type

SET,a22b,0.5 #variables init
SET,a11b,0.3
...
SSPA,a11b,a12b,a16b,a22b,a26b,a66b #define A matrix
#######

How could I do something like that in Nastran?
