    Yes - that would be the restart functionality - provided the number of nodes doesn't change.  (Restart capability depends on the model having the same number of nodes.)  You would set up the model run for the transient and change whatever you want about the model (but not the number of nodes in the mesh) - then go through that Restart portion of Launch panel - as in the image you attached.  The Working Directory would be the working directory for the previous run - by default with the name ACUSIM.DIR.  Then you can select from the available problem, run of that problem, and time step of that run to use as the initial conditions for the new/restart run.

    If the mesh is different, you'll need to go through a different process.
