1. None of your sketches are constrained? I recommend robust modeling techniques before moving on to FEA.
2. I do not see a simulation in the file you attached?
3. The default animation is a scaled exaggeration of results so that change can be clearly be seen. What happens if you set to True Scale?
post some pictures of what you're comparing. my guess is that it is #3 from j mather. have you looked at the displacements and not just the animation? also i think we assume that you reran the analysis and there were no errors.
