<p>After the first email, I played around and find that it is caused
by the average ionization in sesame module. <br>
</p>
<p>FLASH has use Thomas Fermi ionization to model the average
ionization level at low temperature. <br>
</p>
<p>But it is weird that the ionization level at room temperature
come with al-imx-003.ses or al-imx-003.cn4 doesn't match TF model.
<br>
</p>
<p>The minimum ionization level is around 0.015 but 0.02 is used
instead, that is ms_targZmin at work. <br>
</p>
<p>But TF gave around 2.4 at room temperature and ms_targZmin is not
applied. It seems like the code take the maximum value between
ms_targZmin and data.</p>
<p>My guess is that as long as the average ionization level
initiated with too large value it is difficult to get laser
heating. So other table from sesame also dont work.<br>
</p>
<p>I appreciate if anyone or from developers can comment about this.
Thanks. <br>

<p>Dear FLASH developers,</p>
<p>I am running FLASH4.7 using SESAME table for aluminum
(mat id 3720). In LaserSlab par file, ms_targZMin = 0.02.
This is fine by using al-imx-003.cn4, where the z_bar
shows 0.02 for Targ species. But when I use SESAME table
(directly after sesame-extract with opacplot), the z_bar
is 2.461 although ms_targZMin = 0.02 is set. What is the
reason in this case? What is the difference with
sim_zminTarg in config?</p>
<p>When I use "eos_gam" the z_bar is 13.<br>
</p>
<p>The problem in using SESAME is that there is no heating
(I have used BDRY condition), while there is heating using
al-imx-003.cn4.<br>
</p>
<p>al-imx-003.cn4:</p>
