Hello,
I'm working on a problem where I have a structure that needs to be pre-tensioned before running a modal analysis. I am able to accomplish this by using an EIGRL card and a METHOD with the SOL 106. My problem is that I now need to deliver a Craig Bampton model, butI'm not sure how to go about getting this output. Any help on this would be greatly appreciated.

Thanks!

This can be done using SOL 401. One of its capabilities is to run pretensioned/prestiffened modal analyses. Are you able to use SOL 401?
 
AFAIK superelement creation and export works only in SOL101/SOL103.
