The diagram attached shows a model I'd like to investigate because it has some practical importance in therapeutics.  As a biologist not an engineer, though, I admit to being baffled by how to set it up in ANSYS Student, despite spending time looking at the training videos.  The geometry is very simple.  The modeling might be less simple because it has a change of state as well as multiphase and conjugate heat transfer aspects (if I have the right buzz-words .   The air convection contribution to warming the rod might be minor enough to leave out.  If anyone is in a Good Samaritan mood, and feels like setting up this model in a form I can tweak myself, I'd be very grateful.
