what is the best way to simulate all stages of this problem to get force-deflection curve?

Maybe you can have a look to those 2 files [here](https://transfert.free.fr/5JsLdbI)

thank you, but basically my question is about stage 1 to 2. How to make prestressing of the bow, so that bowstring has pretension. I think maybe \*equation/remove may help or something like that.

This is actually used as an example of multistep analysis workflows in Abaqus course materials and documentation. There are 3 steps:

- static with Nlgeom for pretension
- static with Nlgeom for pull back
- dynamic implicit with Nlgeom for arrow release
