Displacement is wrong in Dynamic Analysis

Question asked by Jens Leander on May 25, 2016

Hello!

I am modeling a fixed free beam with a mass on the free end. I am interested in the displacement of the free end.

 

I am giving the free end an initial displacement of 15mm (0,015m). When running the study and making a time/history plot the beam is displaced 0,006m at t=0.

Why is the displacement at t=0 not my initial displacement?

 

Am i missing something?

 

I have attached som pictures and marked my problem in red circles.
