Unbalanced Reaction Forces

Hello,

I seem to be having some issues with the balance between the applied loads and reaction forces on my model, which do not match (file attached).

I was able to locate the issue, it happens when I dis-activate the bending stiffness of the beams ("ModifyElem" component, "Bending" parameter set to "False").

The loads and reaction forces are balanced if I consider bending stiffness, but I'm trying to simulate cable elements. Changing the elements pretension is also interfering with the global reaction forces when bending stiffness is dis-activated.

Am I overlooking something or maybe I have a wrong input? I'm using Karamba 1.2.1 version.

Best,

Pedro Giachini
