How do you create a prestressed superelement? My run is aborting.


You are trying to run a prestressed modal without having
generated the prestress information. There needs to be a static use pass
and expansion pass to create the prestress.

There are two ways to create a stress-stiffened superelement.
In both of these methods, the stress-stiffening is in the
superelement and pstres,on doesn't need to be set in the modal:

Method 1
Generation Pass
Static Use Pass
Expansion Pass (pstres,on)
New Generation (pstres,on)
Modal Use Pass (pstres,off)

Method 2
Full static (pstres,on)
Generation Pass (pstres,on)
Modal Use Pass (pstres,off)

If there are non-superelements in the model. The situation
would be different:

Method 2a
Full static (pstres,on)
Generation Pass (pstres,on)
Static with super-element and non-superelements (pstres,on)
Modal Use Pass (pstres,on)
