Discontinuity Across Shell elements (APDL)
Hello,
I preformed a static structural analysis using Ansys Workbench.
I have been trying to export stresses using APDL commands from a geometry, which is constructed of shell elements (SHELL181).
The geometry is a multi-body (of shared topology mid-surfaces) and the stresses were extracted by PRNSOL command.
As I export the stresses, I see a discontinuity in them in the connection line between the components, as shown in Image1.
The stresses in the workbench are OK and I don't see the same phenomenon, see Image2.
I have tried looking at different layers of the shell (Top, Bottom) but there it still acts the same in the contact between the mid-surfaces.
When I look at each mid surface in the workbench desperately, I don't see anything unusual.
If anyone has an idea how to solve this - please let me know. Thank you

Being said that, are your shells of same thickness?

I use Ansys workbench, Mechanical. I export the data and visualize it in Matlab, but it has no effect on the problem, of course.
Please try to export either Top or Bottom position results and see if you see the same discontinuity. You are currently exporting (top/bottom)

I have tried exporting Top and Bottom separately, the discontinuity remains in both cases. Is there another option I should consider to solve this?
