DMAP - Altering matrix

[guilhermemd11]

I am trying to run a buffeting analysis on NASTRAN using the random gust analysis method. Hence, I need to alter the AIC (aerodynamic influence coefficient) matrix by DMAP coding. I must set the matrix AJJT (which is called in subDMAP SAERO) to be the identity matrix, through statements on the Executive Control Section, using DMAP language.

Does anyone knows how to code in DMAP and could help me? I would really appreciate.
