<p>Hi Paul,</p>
<p><br>
</p>
<p>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.</p>

<p>Hi Adam,</p>
<p><br>
</p>
<p>Can you be more specific? Is it melting? </p>
<p><br>
</p>
<p>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.</p>

<div class="PlainText">Hello,<br>
<br>
I have a conjugate heat transfer problem where the solid material is a <br>
composite that undergoes a phase transformation. Is it possible to <br>
model a material like this in Nek5000?<br>
<br>
Thanks,<br>
