Influence of fixation

Good morning,

I ran two simulations which are alike although I have included the screw fixing my insulation material in the second one, whereas in the first one I did not consider this screw. I wanted to see the impact of the thermal bridge created by the screw.
I was very surprised to see that the results of these two simualtions were very different.
So my question is : Isn't Wufi 2D too "severe" for the integration of screws because of the fact that we are in 2D so the screw is considered linear (like if it were a sheet of metal) ?
Is my second simulation realistic ?
Thank you very much,
