How to select each side of the surface body

    • Ji-Hyun Jeon

      I would like to give heat flux and radiation conditions to both sides (top, bottom) of one Surface body in Transient thermal module.
      Previously, for example, a single layer with a thickness of 50 nm was divided into two surface bodies with a thickness of 25 nm and used after contact (bonded).
      In the multilayer thin film model, the existing method becomes cumbersome. So I wonder if it is possible to designate the top and bottom sides of the shell separately with the command (ADPL) function and give the heat flux/radiation to each side or is there another way.

      I use ANSYS 2022R2 version.

      HI Ji
      You may not find the options to select the different surfaces like top and bottom by using mechanical GUI in the 2022R2 version yet, but this can be possible with the ADPL command snippet in the Mechanical.

      Thanks to your help, I was able to read the document. 
       
      But it's my first time writing a command, so I don't know how to start it. I want to give Heat flux to face 2 (top), Heat flux 2 to face 1 (bottom), and each Radiation to face 1 and 2 (top, bottom). Is there an example to look at and refer to? 
       
      Please help me. Thank you.
