Hello Mr Sampat, thanks for the reply and sorry for the late. I was in holidays so i havent acess to my desk. 

For the problem, i've already applied constraint ( displacement =0) to all directions of my model but i never found the 25.9µm , instead i find 34.3µm. 

For the type of analysis i've run 2D and 3D analysis with constraint on flat surfaces but i never found the good results. 

Screenshoots:

3D analysis:

(Constraints for both surfaces) 

Also tried with fixed support for the BC but i find the same result.

 

2D analysis :
