[yt-users] [YT-USERS] Incoherence when ploting a slice - from FLASH simulation

[Gabriel RIGON]

I've uploaded the dataset: http://use.yt/upload/364c7039

Could one of you share a dataset that exhibits this behavior?

You can use the yt curldrop to share datasets:

Gabriel,

I would like to add that I have seen this problem as well in my own usage of FLASH with yt. The streaks appear to be perfectly doubled in value relative to their neighbors. I would love to hear if anyone in the yt community has seen it and/or knows what might be going on! Note: These streaks are not in the FLASH data; VisIt reproduces the data without the streaks. Also, a yt ray output does not show the streaks; the slice plot does.

Best,

Scott

Dear all,

I recently start to work with yt to analyze my FLASH simulation. The output of those simulation is an hdf5 file.

When I try to plot a slice of my simulation, some weird lines appear on it. Here is an example of the python script and the results it leads to.

"""
import yt

ds = yt.load("lasslab_hdf5_plt_cnt_0000.hdf5")
yt.SlicePlot(ds, 'z', "dens").show()


[cid:972219b9-edbb-4265-81cf-9a07e61cf360]

"""

Actually they also appear went plotting the results of a frb of a slice (even when I try to plot the x or y coordinate in 2d).

Do you have any idea of the reason for such lines, or a solution for my problem?

Best regards,
Gabriel Rigon
