Prescribed Motion to Flexible Filaments

[Chait263]

Hello, hope you are all doing well. Previously there had been an issue regarding giving prescribed motion to rigid bodies which was answered. We implemented it in code and are glad to say that it worked well as expected. We wanted to try and extend this functionality to flexible bodies as well (say a filament for example). Is there any way by which we can give prescribed motion to a flexible filament? For starters, we can try to implement heaving motion given to the leading edge of a filament.
