I am trying to figure out how to simulate a torsional spring to simulate a torsion spring axle. In reality, a square shaft is sandwiched in a square tube with ruber in the corners of the tube. Does anyone have any ideas on how to simulate this? I have seen in the help files, that a torsional spring can connect two verticies. How can you connect it to the center of a square, or round, shaft?
I am using Simulation 2011 Premium.
Thanks in advance for any help.
