Dear Sir Richard Ay,

I would like to clarify the document of how to model can support with friction in the manual. This is what I did.

1. Model a rigid from run with zero weight(ex. y=-100mm) say(node(100-110)
2. at (node#110) Input restrain X,Z,RX and RZ and hanger. all with the same cnode(ex.1110).
3. from other spreedsheet, input a +y restrain with friction which node at node 1110.

Please guide me, because I realy dont know what is the source of the expansion of my rigid element.

Right now Im seeing my node#100 with +y displacement of .311 and node#110 with +y displacement of .249.. Why does this rigid element expand to 0.062mm.

Regards!
