Hello Instead of attaching your images, could you please embed them directly into the post? Ansys employees cannot download images from the forum.
Regarding your question - no, I don't think it makes sense to run a steady-state model and then run a transient model (unless you are changing something in the model after you have your steady-state solution - this is the only way there would be any transient behavior introduced into your model).
Some general suggestions - please reduce the time-step size to ensure proper convergence every single time-step. You might also increase the Max iterations per timestep.
Please share some screenshots so we can provide some specific suggestions.
