"Empty GP result list"

Dear community,
I’m analysing a particular spatial structure made of beams elements and as result of “2d element results plot” I have a red error message with the “Empty GP result list”. deconstructing the model I notice that the GP points are all located along the x axis of the global reference system.
I can not evaluate the outputs of my model but i can visualize the deformated structure.
Any idea on how to solve this problem?
Thanking in advance

most probably: the output of the stress results is not activated. You can do so by plugging a value list into the O input of your analysis component.
