<p class="MsoNormal"><span style="font-size:11.0pt">You have it right. It should work with plot_var_x = varname. For a multispecies simulation, the mass scalars ‘ye’ and ‘sumy’ (related to ionization and atomic mass) work the same way.<o:p></o:p></span></p>

<div>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Tahoma",sans-serif">I'm interested in using a MASS_SCALAR variable to track mixing of material in a simulation. I understand that I need to declare it in my simulation Config file:<o:p></o:p></span></p>

<div>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Tahoma",sans-serif">and then I can access it as:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Tahoma",sans-serif">However, it's unclear to me how to make it so that that data is output to the plot files. Presumably I need to put something in flash.par but it doesn't seem like it should
be plot_var_x = varname<o:p></o:p></span></p>
