3D model PROBLEM

Dear All,

I am writing this post to report some issues I am experiencing with 3D modeling using GEOXPM. I simulated two slopes using both 2D and 3D modeling. Please note that I am analyzing a planar problem; the 3D modeling was performed solely to assess the computational burden of using this simulation methodology.

I successfully resolved the 2D problem with excellent results. However, when attempting to model the problem in 3D, I encountered several errors, which I have attached to this post for reference. I suspect that the issues might be related to the constraints applied to the "FRONT" and "BACK" boundaries.

Has anyone faced similar problems or could provide guidance on how to resolve them?

Thank you in advance for your assistance.

Best regards
