I would like to request advice, how to quickly understand the basic APDL command to be assigned in Ansys Workbench? I saw on YouTube that they did very easy by copying and pasting to the command function, then solving. However, I did the same thing but in error. I need to understand the command details so that I can change any required parameter of my model in that command. Thank you.

Hope this will help you

Dear Zeinah, please try the code below for defining coupling between the nodes that belong to solid and shell elements. I wrote the code for all DOF, however, you can use what you need. Let me know any problem with this issue, good luck.

!======= CODE BEGIN =======

n=1      ! arbitrary Constraint Point number
