Issue in importing 2D geometry for structural analysis

      Hi , 

      I am trying to carry out a structural analysis with 3d and 2d geometry and compare the results.

      I want to use plane stress analysis for 2d geometry. But I am getting this error when I try to edit the model cell from Ansys mechanical.

      3D analysis is working fine.

      I changed the analysis type from 3d to 2D in the geometry property.

      I tried in ansys 2021 R2 and 2022 R2. I am facing same error.

      Do you have any suggestions for me?

      Regards,

      You cannot change an existing model from 3D to 2D. It doesn't work. I don't know why.

      To build a 2D model, you must start with a new Static Structural model, and on the Geometry cell in Workbench, set the Analysis Type to 2D before you open the model.  I assume you have sheet bodies in the X-Y plane with Z = 0.  That is another requirement.

      Thanks, You are right. I think there was an issue with my geometry. Even though it looked in x-y plane it was not taking. After redoing the geometry it worked.
