      Hi everyone, I am currently trying a simulation with the AM Process for DED tool and am wondering which temperature source or model it is based on. is it Goldak? Or does anyone know where I can find out?
       
      Also, is it possible to make modifications to the temperature source through parameters?
       
      many thanks

      DED does not use the double-ellipsoidal heat source model (proposed by Goldak).

      You might be able to write a user routine.  Please see MAPDL Programmers Reference Manual for details.

        Hi John Doyle,

        i can´t use the Link you sent, because i have only an student license. I can´t finde a account number.

        Which heat source model does DED use? 

        I already tried a apdl code in combination, but they could work with each other.
