Why simulation results interfere?

Hi all,

 

I did an analysis but I am in a little confusion whether my readings are correct or not due to following reason.

 

1. In one case, I added contact set "No Penetration" and run the analysis - I got one set of results for key and key way

2. In second case, I added contact set "No Pentration" and added displacement "0" (Radially and axially for key and key way relatively) then run the analysis - For the same case.

 

I found huge difference in readings.  Which case should I prefer?  When we run the analysis, should we consider applying fixture -> use reference geometry -> key surface fixed w.r.t keyway surface or not? - **After applying contact sets**

 

Please share your idea.

 

Thanks
