[Nek5000-users] Conjugate heat transfer with complex properties

[nek5000-users at lists.mcs.anl.gov]

Hi Paul,


Yep, there's some melting going on.  There's a porous structure that 
does not melt and wax trapped in the porous structure.  The wax melts 
and re-solidifies.  There really nothing complex happening with the 
geometry.  A static mesh should do the job. The material properties are 
the challenge.  I think I could model the material behavior as having a 
non-linear specific heat capacity as a function of temperature.
