Hi Zhang,
<div>
<br>
</div>
<div>
I've also found that only the first 9 "plot_var_"s are put in FLASH<span style="font-family:SimSun"> "*plt_cnt*" output files</span> (but checkpoint files contain all variables). I'm not sure if this is intended behavior or if it's been fixed in later versions (I'm using FLASH4.2.2). What version of FLASH are you using?
</div>

<div>
If you also cannot access "cond" from the checkpoint file, then you can check Flash.h (in the object directory) for the name of the variables your simulation is following.

<div>

<div>
Also, since you mentioned using VISIT I wanted to mention that yt is another great option for FLASH analysis and visualization:

<span style="font-family:SimSun">Hi!</span>
</p>
<p>
<span style="font-family:SimSun"> Usually, the output files of FLASH are the database of some variables like "dens", "temp", "pres". We can check it by importing the database to VISIT. However, what should I do if I want to put other </span><span style="font-family:SimSun">variables into the database of output files.

</p>
<p>
<span style="font-family:SimSun"> It seems that there is a plot options in flash.par just like</span>
</p>
<p>
<span style="font-family:SimSun">### Plot Options ###<br>
plotFileNumber = 0<br>
plotFileIntervalStep = 100<br>
plotFileIntervalTime = 0.01e-09<br>
plot_var_1 = "dens"<br>
plot_var_2 = "depo"<br>
plot_var_3 = "tele"<br>
plot_var_4 = "tion"<br>
plot_var_5 = "trad"<br>
plot_var_6 = "ye "<br>
plot_var_7 = "sumy"<br>
plot_var_8 = "cham"<br>
plot_var_9 = "targ"<br>
I set a new plot_var_10 = "cond".(conduction) But it seems that it does not work? What else should I do?<br>
