Manually Controlling Time Steps in OpenSees

[aminasareh]

Hi all,

Does anyone know if there is a way from TCL to manually control time steps in OpenSees? In particular, can you step back a time step to re-try an analysis of the current time step?

Thanks

if the analyze command fails you are automatically returned to the last ok step .. if it works, there is no way to go back.

Thanks Frank.

But for using OpenSees in hybrid simulations, I guess you have to be able to control timesteps in simultaneous integration times between programs. How does OpenSees work there? Is there a way to keep OpenSees open during each analysis that is comunicated between multiple programs? Should the OpenSees code be changed for using OpenSees in hybrid simulations?
