S&S vs Straus7 vs ANSYS

Hi,

Finally I have found some time to make a small SnS test. I have taken the steel part from my last post and checked it in Straus7. The brick mesh I made in Straus is quiet nice and clean and the SnS resolution is reasonable.

Now the results: The deflections are similar in size, but the shapes are a bit different (the zero displacement spot in Straus is in the middle of the plate, in SnS a the upper edge of the plate). The stress peaks are at same places, but the stresses are very different. Checked loads, checked material, checked restraints, checked model, checked analysis type - all the same between SnS and Straus.

Now I am a little bit confused, which one of the results is closer to reality? What could cause those differences?

Cheers,

Hrvoje.
