Convergence problem during dynamic analysis

[aenils]

Hi,
my dynamic analysis did not converge at higher scale factor(>1.0).
I have paste output from the opensees.

OpenSees > source dynamic.tcl

Let me know the solutions for the problem I am facing.
Thanks

same error occured in my analysis ，how did you solved it ？

add some alternative algorithms to the nonlinear script in event of failure.
