Help with Ansys Steady State Thermal Analysis

  Hi! I have some questions about setting up the boundary conditions for steady state thermal analysis. I am modeling a copper cylinder at 250 C radiating to a heat flux gauge (which I model as a small stainless steel disk).
  Can I define two boundary conditions on one surface?
  Should I define temperature across the entire cylinder and then have it also radiating surface to surface with the disk, or should I only define temperature on the top half of the cylinder?
  On the top half, can I have convection, radiation and temperature as conditions?
  Finally, I am a little bit confused by the different outputs I can get from a solution. What is the difference between total heat flux and directional heat flux? And how do these differ from the results I get with a radiation probe on either surface?
  
  Thanks for the help :-)

  Friendly suggestion, don't post in multiple threads. It annoys the moderators.
