running transient conjugate heat transfer case

[pei-ying.hsieh]

Dear Autodesk experts,

I am running a transient conjugate heat transfer case.  I had both flow on and heat transfer on and then, started the solving.  The case diverged each time.  Then, I noticed in the transient tutorial, it solves flow only to steady state, then, turned off flow and heat transfer on and solved for transient.  This approach did get me transient results.  But, flow might be affected by heat tranfer.  So, why using this approach?  And if I need to turn both flow on and heat transfer on, then start transient run, what will be recommended settings to ensure a converge solution.

Thanks!
