I have an APDL input file that has SHELL209 elements that I can see in the Mechanical APDL classic GUI.

This is an axisymmetric model with a pressure load and a Y constraint at the bottom.

I can solve it and plot deformation results.

I want to import this model into Workbench and view it in Mechanical. In APDL, I used CDWRITE,DB to create a .cdb file.

In Workbench I added an External Model and pointed to the .cdb file. I dropped a Mechanical model on that and got this error.

I noticed is that the Properties for the Model cell had Analysis Type set to 3D but I get the same error after setting it to Analysis Type 2D. Is there something I can change to make this work?

Here is the APDL input file:

Hi

 

Do not think these type of 2D line axissym.elements are supported inside wb mechanical (indicated also by error msg) – thus use 2D elements like plane182/183 which are.

 

All the best

Thanks Erik.
