<p class="MsoNormal">I am attempting to get the 2D Z-pinch problem working with AMR but have been unable to get the sim to run without crashing . From the logs, I appear to be running into many negative internal energy warnings. It looks like both the electron
and ion temperatures/energies need to be continuously corrected. To try and address this issue, I have tried refining on density, electron, and ion temperatures but the warnings persist. In terms of the AMR settings, I am using a 32x32 grid with 4x4 cells,
a lrefine_max=4, and I have left the refinement cutoffs and filters unchanged from default. My questions are:<o:p></o:p></p>
