Re: about the "plane stress/strain thickness" in 2D model

The thickness parameter scales all forces in the analysis.  Applied force 
bc's for example are by default "per unit thickness", but if you provide a 
thickness parameter the forces need to be scaled appropriately.
Likewise for output reaction forces, etc.

If you handle the bc's correctly the stress result should be exactly the 
same, although I can imagine there are cases where the scaling impacts 
convergence.
