Thank you for posting your model. With a DAB topology, I suppose the system itself is periodic, but I would actually expect the variable phase shift nature of the control scheme to prevent the Steady-State Analysis from providing a proper solution. I think that would be true even if you ran a transient simulation to steady-state conditions, then saved the system state, and then used that saved system state to run a future Steady-State Analysis. If, however, you don't actually need to use the Steady-State Analysis tool, but just want to start a transient simulation from a script where the initial state variables are assigned their steady state values, you can certainly do this from the Simulation > Simulation Parameters menu, in the Initialization tab of that window (it looks like you already were exploring this option as there is a previously saved state). You just need to select the "Stored system state" as the system state that the solver initializes from, which was not the case in your model. I hope this helps!
