Hello,<div><span style="white-space:pre"> </span>Here I have written a simple matlab script for such conversion, I use sesame Sn data and the output .imx file have been tested in FLASH LaserSlab expamle, with actual run completed successfully. You need to choose your desired [rho,T] grid and the script will interpolate [Pressure, Internal energy, Rosseland, Planck] on that meshgrid, then produced a file in ionmix4 format.</div><div><span style="white-space:pre"> </span>But there are some problems for this version you need to be aware of: </div><div><span style="white-space:pre"> </span>1. I don't have sesame table containing ionization, so Thomas-Fermi ionization is used here, the error can be significant(20% at most I suppose?).</div><div><span style="white-space:pre"> </span>2. Extrapolation (here I set a small constant extrap_val = 0.1) can happen if you use meshgrid cover a larger [rho,T] than original input grid. For example, the opacity data I have begin with temperature ~ 4eV, so the output imx file is not accurate when start from room temperature.</div><div><span style="white-space:pre"> </span>3. I only have one radiation group in my sesame table, or a "gray" radiation field. If you need multiple groups you have to make some changes to the script, just repeatly write-out each radition group consecutively in the same format.</div><div><br></div><div><span style="white-space:pre"> </span>And also to mention, on this link:<a href="http://flash.uchicago.edu/pipermail/flash-users/2015-April/001689.html" target="_blank">http://flash.uchicago.edu/pipermail/flash-users/2015-April/001689.html</a>, Roman suggest using opacplot2 to do the conversion, I tried but I always get the segmentation fault problem, guess I didn't install those librarie right or something. Maybe you can try it first, for better confidence.</div><div><br></div><div>Best,</div><div>Tao</div><div><br></div><div><blockquote name="replyContent" class="ReferenceQuote" style="padding-left:5px;margin-left:5px;border-left:#b6b6b6 2px solid;margin-right:0">-----原始邮件-----<br>

<p style="margin-top:0;margin-bottom:0">I am trying to use SESAME EOS tables+opacity tables of some low Z materials in FLASH. Has anyone had the experience of converting SESAME tables into IONMIX4 format and use them in FLASH?</p>
