In transient structural, what is the difference between applying a load that varies in its magnitude over 1 step vs multiple time steps (like 10 steps, for example)? Which method is considered more conventional? Please see the picture below for your reference. Both represent a simulation of 1 second.
Also, I will be coupling this transient structural with fluid flow (Fluent). Would the "1 step method" or "multiple steps method" affect convergence during coupling?
Thank you so much for your help.
