Where would I start for modeling something like a waterbed? Say a 2D well-shaped object with an incompressible liquid covered in a surface, like a 2D waterbed.
Basically bound at the edges, has some ability to stretch to allow curvature, but will not compress the liquid(the area/volume of liquid in the picture would remain same). I'm looking to do some statics, not dynamics too, so that should make it easier.
Would stuff like the depth of the well affect displacement of the surface? Or is it all in the elasticity of the waterbed and the length?
Like say you have the situation where the left side is 1m high, the right side is 2m high, and the top part is stretched between the two, filled with liquid in a gravitationally free environment to make a linear gradient between the two, then its placed into gravity where the surface has some mass and elasticity, so it would sag some, and probably be exponential/y shaped from point A to B.
Where would I get started with this? Is this fluid dynamics/statics? Is it materials? Topology? etc.
(Writing the simulation code is the easy part, I just need some governing principles)
