Strange lines appear when using visit to visualize

[tianninglyu]

I use the problem generator jet.cpp and the input file athinput.jet, and visualize the data with visIt. When I use vtk to output, everything is correct. However, when I turn to use hdf5 output, strange lines appear. Here is the image.


I have three conjectures: 1. it is due to the output format; 2. It is due to parallel computing (HDF5 output files are obtained by parallel computation while vtk output files are not); 3. It is due to the visIt software.
I wonder if you have some experience about that.
Thanks!

Have you tried 1) plotting the HDF5 files in matplotlib or another alternative? and 2) running without MPI?

What does your <output> parameter block look like for HDF5?

I have tried to visualize the hdf5 data with the yt python package, and everything goes well.

I have tried running without MPI, but when without MPI, I use vtk output but not hdf5. In this case, the data can be visualized correctly with visIt.

The output is as follows:

output1
file_type  = hst      # History data dump
dt         = 0.1      # time increment between outputs

output2
file_type  = hdf5      # Binary data dump
variable   = prim     # variables to be output
dt         = 1.0      # time increment between outputs

Best wishes and thank you for your consideration.
