Size effect on modelling Plaxis 2d

Hi,

Why when the model size have effect on the results even for huge dimensions? known that no deformation is happening below 4B of the footing.

Actually I am trying to do sensitive Analysis for my then I used 100*100 model size just to see if there are any effects in the Load-settlement results

I found that with every-time I make my model bigger it gives me higher values !! even I tried 1000*1000 and as well have affects

(I am simulating other's work, and my results is the same as them at (X=20 Y=10) but when I started playing with model size things changed.

Model/ learning to find the ultimate bearing capacity of strip footing on sand.
