How to design a plate with displacement control in following logic:
Add 0.2m/s velocity if resistance force is lower than F (initial value 50N).
If F is not enough, add 50N to F and cycle again.
End all if total displacement reach 0.8m.
Using optistruct explict solver.
Currently there's no way to accomplish this automatically. You would need to run iteratively and adjust, or create a study inside HyperStudy to adjust your model.
