<p class="MsoNormal"><span style="font-size:12pt;font-family:"Times New Roman",serif">I am a new user to FLASH. I am planning to run a 2D simulation with
<b>half a million meshblocks</b> with a fixed <b>size of 64x64x1</b> cells using Paramesh. I plan to use FLASH’s HDF5 format for visualization in VisIt. From a visualization standpoint, I want to know how many output files per frame do I need to write the HDF5
output so that I can comfortably visualize the simulation data in VisIt using the FLASH database plugin.<u></u><u></u></span></p>
