i've been playing with lightSys+hcrEdit, which does kill time very well. :-)

-it does runs in 1.1, but yes, i had some stability problems.
-i will try with very soft connections.
-i know that the simulation will not be very realistic, for a
 start the mass is not distributed evenly threwout the bolt.
 I was actually only interested in the final result: a pile
 of (non-moving) bolts.
-i will add more masses along the thread of the bolt and add
 faces, and then do mass-face collisions. i guess the increase
 in number of masses will be compensated by a more stable
 simulation, which allows for larger time steps.
-i'm still wondering why the connection-connection collisions
 dit not work, even with near-instability the system should at
 least do something. is it possible that the connections end
 up with a zero radius, even if they are drawn with a large
 radius when rendered?
-i picked 3 (perpendicular) masses from the simulation and
 converted there position to a matrix, which positions the
 iso-surface bolts: http://jwstolk.afreehost.net/bolts_test.jpg
 (the bolt-head in the simulation was bigger, and the radius of
 the masses was not counted for, which leads to the "hovering")
jaap.
