[FLASH-USERS] Error writing initial HDF5 checkpoint and plot files

[Deepali]

Hi Ryan,


I am using FLASH4.6.2. I tried other available HDF5 versions - 
hdf5/intel/1.12.0, hdf5/intel/1.12.1 , but received different errors 
with 10.5 and 12.x (tried with -DH5_USE_16_API, -DH5_USE_110_API, 
-DH5_USE_112_API).

I also went through the mailing lists where a patch was made available 
for FLASH4.5, but it didn't work for me.

Could someone tell me which library versions are compatible with FLASH 
4.6.2? Is there a documentation available for the compatible HDF5 
library and FLASH versions?


Best,

Deepali
