n2D Plane Strain elements are not Shell elements. If you do a 2D Plane Strain model, when you pick an edge of the domain to apply a Fixed Support, that is like picking the face of a solid body. This is very different than picking the edge of a shell element in 3D.nAs you make the elements smaller and smaller, the unaveraged element stress will go closer and closer to zero on elements near the center of the fixed edge. However the two elements at the start and end of the fixed support are singularities, and those elements will not approach zero unaveraged stress.nMake a 2D Plane Strain model that looks like this to investigate.n
