I installed VisIt 3.1.0 from the link. I tried running the visualization
script with it and that gives me errors. The issue still seems to be about
reading Carpet HDF5 files.

VisIt: Error - VisIt could not read from the file "/afs/
crc.nd.edu/user/a/akedia/simulations/nsnstohmns_in_saeng/output-0000/nsnstohmns/rho.xy.h5
".

The generated error message was:

There was an error opening /afs/
crc.nd.edu/user/a/akedia/simulations/nsnstohmns_in_saeng/output-0000/nsnstohmns/rho.xy.h5.
It may be an invalid file.
VisIt tried using the following file format readers to open the file: <No
suitable plugins were identified>
VisIt: Error - Cannot create a plot until a database has been opened.

For assurance, I checked that the installed version of VisIt 3.1.0 has a
folder on CarpetHDF5 in :
visit/3.1.0/visit3.1.0/src/databases/CarpetHDF5
Should this be the only folder with CarpetHDF5 created?

On trying to load a file on Visit GUI I get this error message:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

The generated error message was:

There was an error opening /afs/
crc.nd.edu/user/a/akedia/simulations/nsnstohmns_in_saeng/output-0000/nsnstohmns/rho.xy.h5.

VisIt tried using the following file format readers to open the file: <No

And when I'm selecting the file, there is no option for CarpetHDF5 in the
dropdown list of supported file name/extension.

Thank you for your help,
Atul
