  I'm using ANSYS APDL.
  
  I want to do analysis about a time varying temperature loading thermal-mechanical analysis.
  
  Generally, coupled thermal-structural analysis is used for it.
  
  Firstly, thermal analysis is completed and then, followed by structural analysis.
  
  I have interested in thermal analysis as below.
  
  1. A PCB strip is pre-heated in 220'C bake.
  
  2. The PCB is cooled down to 25'C
  
  3. The PCB is re-heated to 260'C
  
  But, I want to use nodal temperature not heat flux as loading, in the menu path 'solution>Define load> apply>temperature' load temperature.
  
  and I want that temperature distribution is even because it is steady state, (just it is different by time not location).
  
  How can I make the solution.
