On 'capture3' image, it is clearly shown that the top/bottom faces of shell are not properly aligned. That's why results in that region are upside-down as if ,for instance, you demonstrate stress results on bottom side of shells. To flip those faces, click on it, then right click on 'mesh', select flip shell.... Furthermore, please pay attention which side of shell (bottom/top) is chosen to be shown for results (eg. stress/strain). You can also render results in 3D.
Thanks for your answer
However even if the top and bottom faces are properly alined I can't get correct results. The problem of discontinuity constraints persists.
I tried to reduce the mesh of the zone T, but without correct results.
The entire geometry can not be designed and meshed in 3D because it is too large (25m) and the parts are very thin (10 mm).
