Replicating Thrust Line Calculation with Kiwi3D in Grasshopper

I am attempting to replicate the thrust line analysis presented in the paper "Thrust Line Using Linear Elastic Finite Element Analysis for Masonry
Structures ". Instead of the traditional approach described in the paper, I am using Isogeometric Analysis (IGA) and the Kiwi3D extension in Grasshopper.

While I have set up and completed the analysis using Kiwi3D, the results I am obtaining are not matching those in the paper. Specifically, the calculated thrust line is different from the one presented. I suspect there might be discrepancies in how I am defining:

  1. The boundary conditions.
  2. The loading conditions or how the IGA method is implemented within Kiwi3D.

I have attached my Grasshopper file for reference. I would greatly appreciate it if someone could review my setup and help identify any potential issues.

Has anyone here tried a similar workflow or encountered a similar challenge? Any insights, tips, or suggestions to align my results with the paper’s findings would be invaluable.

Thanks in advance for your help!
