Dear experts,

If I understood well here https://manual.karamba3d.com/3-in-depth-component-reference/3.5-algorithms/3.5.2-analyzethii , the Analyze ThII component uses the highest normal force from all Load Cases to account for the geometric stiffness 2nd order effects.

I’m sorry, but I really do not understand why there it is said:

“The advantage is, that in the presence of several load-cases one can chose for each element the largest compressive force as NII. This gives a lower limit for the structure’s stiffness. A re-evaluation of the load-cases using these NII values leads to a structural response which is too soft. However the different load-cases may then be safely superimposed.”

Shouldn’t the Analyze ThII component use the normal force of each LC to compute the displacements and stresses for each corresponding LC? Is there a way to do so?

Thank you very much in advance!
