I am facing this warning while trying to execute the analysis of my stone masonry model: I have created interaction between the walls and applied translation constraints. Also, I have inserted interaction between the timber base and wall at roof level (although, not sure about this). The wall element is thick shell. I have tried to follow similar procedures from the STKO webinars. I'd be grateful for any help with the model that I have attached below:

From the error it looks like that you are using a quadrilateral mesh with quadratic displacement interpolation (9 nodes)
while the element you are using is a 4 node element (ShellMITC4).

You have 2 options:
1) If you want to use quadratic displacement interpolation, use ShellMITC9
2) if you want to use linear displacement interpolation, use ShellMITC4, go in meshControls and use Order = "Linear"

Let us know if it works, or if you have other issues
