<p class="x_MsoNormal"><span lang="EN-US" style="font-size:12.0pt">I think the Zpinch example includes 3 kinds of materials. 1). Deuterium, (sim_fill_), 2). Beryllium, (sim_line_), 3). Low-density Beryllium (sim_vacu_). The low-density Beryllium is used to
simulate the vacuum. You are right. The "Be-006-imx.cn4" and "DD-006-imx.cn4" is the materials’ equation of state (EOS) and opacity which used in FLASH.</span>

<p class="x_MsoNormal"><span lang="EN-US" style="font-size:12.0pt">For your second questions, the IONMIX4 code could be used to generate other materials’ EOS and opacity such as Xenon and its format can be directly read by FLASH. You can find more details in
this paper: “<i>IONMIX - A CODE FOR COMPUTING THE EQUATION OF STATE AND RADIATIVE PROPERTIES OF LTE AND NON-LTE PLASMAS</i>”.</span>

I am using FLASH ZPinch simulation while encountering several puzzles. </span></p>
<p style="margin-bottom:12.0pt"><span lang="EN-US" style="font-size:10.5pt; font-family:"Arial",sans-serif"><br>
1. Zpinch example file includes "Be-006-imx.cn4" and "DD-006-imx.cn4",these 2 files seem to be data related to state of quation and opacity. I cannot figure out which element is used to simulate zpinch, is that Hrodrogen? And Be is for background gas(in vaccum)?<br>
2. Based on puzzle1, if I would like to replace zpinch simulation target/fuel(like Xenon) and background gas, where I can get those data in IONMIX4 format?<br>
3. I tried both 1d and 2d zpinch simulation, but it seems no huge differences in visualized result of parameters like density, pressure,etc. And I tried to read two
<strong><span style="font-family:"Arial",sans-serif">flash.par</span></strong> files intensively and compared with each other. I found some variations in mesh parameters, like in 1d case there is only increment in x direction. 2d case has increments in both
x and y direction. However, when plotting in yt, these variations seem to disappear. In other words, one can plot 2d figures in 1d case. Any nice solutions? I am using yt in Jupyter notebook.</span>
