For my Master’s Thesis research I’m searching the optimal shape of an arch with a given pre-stress.
I think that the analysis method implemented into Kiwi3D could be very helpful in this case.
I’m looking for the best way to define the prestress for a given “beam” element.
I tried to set the prestress as a list of four values, (I think these four values represent the amount of prestress on the vertex of the cross-section) assuming values in kN. Perhaps I assume (10, 10, 10, 10) as a pre-stress due to a cable along the centroid axis.
So, I consider negligible mass, so I don’t have gravity load, but I would like to see only the effect due to the prestress, in this case uniformely compressed, but I get 0 as Normal stress on the beam element.
Alternatively I was considering to couple, if it’s possible and would make any sense, the cable element with the beam element. But as I see is possible set the pre-stress directly inside the “beam” component I think there should be some issue.

If there is someone able to help me, would be really appreciated.
Thank you very much for the support.
