failure index and strengh ratio in random analysis

[Max96]

hello to all, I am in the middle of an exercise, with the use of patran-nastran. the request of the exercise is to find strengh ratio and failure index when a random load has been applied to the structure. on internetmi is recommended to insert in the bdf file the param,post,1. despite this command the strengh ratio do not come out, and I am stuck at this point for a few days, would anyone kindly have any advice to give?

I'm probably late. Do you still need help?
In any case, it seems to me that patran cannot plot strength ratios but it seems that however it is possible to plottartli in the f06 file if you write in your input deck param,srcomps,yes.

do this after you let go of the run you have to go look for the elements in the f06 file for the various ids (if you have so many I suggest you write a macro that does it or use excel) and read them there directly without passing by patran.

I hope I've been of some usefulness!
