how ansys shell63 calculate nodal stress from gauss pt for dkt element
(OP)
In the ansys menu, it stated: a linear square fitting precedure to calcualte the nodal stress from 12 gauss point of the four discrete kirchhoff element. I tried and the resulting nodal stress do not perfectly match with results althrough I am sure the gauss point stresses are correctly calculated.
Anyone know how ansys do this part?

I would think the error could be due to a variety of reasons (the fitting technique for one).

I have figured out the problem. But Ansys does not use the calculated displacement to fit the node.
