Transient thermal with no convection, only internal conduction

      Hello,

      I would like to model a body with an initial temperature distribution and let it reach steady state only from internal conduction.  It would esentially be insulated to the atmosphere.  Any suggestions on how to do this? I try using a heat transfer coefficient with a value of 0 in a Transient Thermal analysis and it does not seem to like it.

      Hello,

      Where does the initial temperature distribution come from?  Is it imported from another analysis or an external data file?

      The default condition for any surface that has no boundary condition is that it is insulated, so you don't need to apply any boundary conditions.

      Is there a problem running the transient thermal?

      It comes from another analysis.  It seems ANSYS won't let me run a transient unless I speficy a boundary condition.

      You can apply a zero Heat Flux boundary condition to all surfaces, which is what they have by default anyway.
