changed between FLASH versions and this changed fixed the issue you’re having for me.<u></u><u></u></span></p>

<p class="MsoNormal">I have recently installed the new version of Flash and I am trying to get the Z-pinch example running. Everything compiles and runs ok however, when I use python to parse the h5 files and make a movie of them, this is the result. It appears
that the current file did not load because the density wave moves away from the z-axis and not towards it. Additionally, when I plot the magp and magz values, they are all zeros. The only step I differed then on the users manual was<u></u><u></u></p>

<p class="MsoNormal">I had to leave out the +hdf5typeio because I did not have the parallelized version of hdf5 of this and it would not compile. Is this the reason for the test problem not making sense.
