Howdy!
I am a new user to FLASH. I am planning to run a 2D simulation with half a million meshblocks with a fixed size of 64x64x1 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.
I have previously tried a 2D sod problem with 130760 meshblocks (of fixed size 64x64 cells) and tried to write a single output file, however, when I tried to visualize this single output file in VisIt 3.3.2 using the FLASH plugin with 512 cores, the file opens but when I do a simple pseudocolor of density, it just hangs and never renders the plot.
Can you please provide me some input on how to visualize large HDF5 datasets from FLASH in VisIt?
Thank you very much.
