Model a hanging net from a square outer curve and a circular inner curve

Grasshopper Kangaroo

I want to model a relaxed surface that is drooping slightly between this square outer curve and the circular inner curve (so there’s a hole in the middle)

Both of these curves are planar, so the net will droop slightly just due to gravity, depending on how “tight” the anchor points are.
I’m assuming the first step is to create a mesh like so. I can extract the vertices that lie on the inner and outer curves which become my anchor points.

However from this point I am unsure how to proceed. If I feed these points into the anchor component, and the mesh into the “show” and "edgeLength: components, and then feed those into the kangaroo solver, the mesh doesn’t deform at all. I’m assuming that’s because it is only calculating how the mesh stretches between these anchor points which are all coplanar (so the resulting mesh will also be coplanar). I’m guessing I need to somehow add gravity as a factor in the calculation, since that force is what will actually cause the mesh to droop? or somehow simulate how the mesh “hangs” from these boundaries.

I’m completely new to kangaroo so I have no idea how to do this, if anyone can offer advise. I’ve tried finding other examples and videos, but the tutorials I’m seeing only really show how to create a mesh that is being stretched from different points that are not coplanar.

I managed to figure it out on my own. I’ll post my solution here for reference:

All I had to do was add a “load” as another goal for the solver. So I applied a negative Z factor to each point on the mesh that is not an anchor point, and voila.
