Hi all, I though I figured this out, but after the run, it is still displacing incorrectly

I have described a displacement boundary condition on an analytical rigid surface that starts from 0,0 (time(s), disp(mm)) and ends up at 1,-5 using a tabular amplitude. The problem, is at the end of the 1 second dynamic step, the displacement is -5.283 mm not -5.0 mm. Any idea why this is happening or what could be the cause?

Thanks in advance,
Chris
 
Do you have only 0,0 and 1,-5 or do you also use some other values in between?
