Hello, I'm trying to model a culvert. The idea is to check the Axial, Moment and Shear in the structure at different backfill stages.
The script below is in the final condition but there are already some lines for the phases.
Even in the final stage only I'm struggling. Also I tried to excavate all the material and to check the arch only since I know the results I should get. But still no convercenge (or no correct effort laws)

Hi, Could you please attach the script file instead of copying and pasting the commands into the message body?
