Is it possible to do a large-deflection prestressed harmonic analysis (full method) similar to large-deflection modal? "A prestressed analysis may not be performed when the previous analysis had NLGEOM,ON."


It isn't a standard feature, but the following input script shows a workaround using the UPCOORD command to
provide the large deflection geometry. That allows a normal prestressed harmonic to be used.

/solu
antype,static
nlgeom,on
solve
upcoord,1
neqit,1
pstres,on
solve
fini
/solut
antype,harm
pstres,on
