I've been looking for some good simulations of spring-mass networks with customizable parameters. Those I find are usually fairly simple, with uniform masses and springs, each connected at right angles to adjacent masses (i.e. six connections from each face in a cube setting, which is the most complex simulation I could find). I would like to explore the dynamics of a less uniform system, i.e. the effect of a large mass with many connections to smaller masses, how those smaller masses respond if they are more interconnected, etc. So I was wondering if anyone has some suggestions for a good simulation tool that they may have stumbled upon during some coursework or similar? I am in particular interested in the visual representation of the time evolution of such a system, so some kind of tool that generates an animation would be ideal.

Is my best bet perhaps to use the physics engine of e.g. the Godot game engine (Jolt physics) or whatever solver is used in Blender?
