Our true stiff-string model (not pseudo or hybrid) with full post buckling calculation enables to simulate "properly" the mechanical behaviour of any string, such as Tubing String. 10 years of research with lab and field data to validate the model.

), as we could run your case in our software to really see the stress and buckling situation downhole. XLS export from Landmark should be sufficient for us to run the model.
