Dear all,
Iam performing a nonlinear analysis for a cantilever column.After the time history analysis, I found the moment of the free end of the cantilever column was nonzero value.I can not really understand this phenomenon.The user manual states taht the moment is provided for the end-nodes of each element(referred to as A and B).These A and B are referred to integration points? would you please explain this phenomenon for me.Certainly,any answer would be appreciated greatly.

Dear langxuzeng,

Have you tried "playing" with mesh refinement (i.e. subdividing your cantilever in more and more elements in case of 'infrmDB', or using more and more integration points in case of 'infrmFB'), as a means to help you understanding what might be happening (reading as well the corresponding sections of the Help System/User Manual)?
