The results of Submodel and coarse are different

[Lirock]

Hi,everyone:
I simulated a big model with shell element, and found stress in the fillet is high,see fig.1 and fig2. Then I used shell-to-solid submodel method to analysis the region around the fillet, but got a very different result,see fig 3 to fig5.
In my opinion, the result of submodel is more accurate,but not sure. Would you please give me some advice?

Liweisc,
You need to host the pictures on a site then tag your post to have them posted in your thread.

As far as your submodel goes check displacements at the cut boundaries and verify them against those in your coarse model. Remember you need to apply all other forces and surface loads as well...not just displacements. Are your cut boundaries far enough away from the area of interest?
