Hi Alice,<div><br></div><div>I have two questions --</div><div><br></div><div>1) Is your simulation being evolved with periodic boundary conditions?</div><div>2) Did you allow yt to choose the point of peak density as the center of the PlotCollection?</div>
<div><br></div><div>If the answer to these are no and yes (in order) then I think what's happening is that the center of the PlotCollection is off, and yt is applying periodicity, which shows up as what you're seeing. Can you try:</div>
<div><br></div><div>pc = PlotCollection(pf, 'c')</div><div>pc.add_slice("eint", 0)</div><div>pc.save()</div><div><br></div><div>I think this might just be a trick of how it's centering the data.</div>

Good morning,
<div><br>
</div>
<div>I am currently working on visualization from Flash Data. I am using Slices of the internal energy along the x-axis. I have a weird line at the top of the slice (see attachment). That looks like a periodic boundary conditions problem.</div>
<div><br>
</div>
<div>The thing is, I don't know whether it is a problem in my code or that I am using yt wrong. I feel like is a plot problem, I looked at the data with another visualization tool (Visit) and it doesn't seem to have this line ...</div>
<div><br>
</div>
<div>Thank you for your help and have a great day,</div>
<div><br>
