Hi Raul ,
hum .. still missing the point
to me it looks like a force field  ( potential )  .. having a minimum 
at  R ( which you define as rest length )
So..
1. what is the point in having a potential  arranging  a mesh close to a 
S3 (sphere in 3D )
2. the lack of other forces .. like friction to surrounding media .. 
even internal friction ..  makes it look quite. say .incomplete
but still
may be i am missing the very spot, enlighten me
