I'd suggest not completely:
Can anyone explain how the weighted link takes the displacement of the independent side and determines the dependent side, and then how it propagates forces? Is it a uniform distribution or is it non-uniform across the independent surface? Why does the location of the dependant point matter?
The quoted help text explains that the motion of the dependent point is the average of all the independent geometry (I assume taken as elements of a 3D body, rather than averaging the individual translations, otherwise the moment balance wouldn't work) but it doesn't explain how forces are transferred back the other way.
I'd like to know this too - at present WLs are a bit of a 'black box' to me in this respect. I know what they do conceptually, but not the specific maths.
I assume that for force propagation they work in the same way as Total Load At Point - but I don't know exactly what that is either!
