Awesome, thank you Paul. Adam On 08/03/2017 11:19 AM, [email protected] wrote:
Yes - that should work.
Set ifuservp = .true. and then, in uservp()
if (ifield.eq.1) then ! fluid properties
udiff = param(2)
utrans = param(1)
else ! thermal properties
udiff = your diffusivity
utrans = your rhoCp
endif

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.

Hi Adam,
Can you be more specific? Is it melting?
In principle, it should be possible as that was one of the original applications for Nek5000. In practice, however, I would rate that as still a research area (at least from the Nek perspective). I guess that melting is much easier than freezing, however.

I have a conjugate heat transfer problem where the solid material is a composite that undergoes a phase transformation. Is it possible to model a material like this in Nek5000?
Thanks,
