[Users] NSNSTOHMNS(Gallery example) Plotting issues

Mon Jan 27 16:10:29 CST 2020

Hello Roland,

Thank you for your email.
I have VisIt 3 and ETK Mayer downloaded which I believe doesn't have
CarpetHDF5. How do I use the CarpetHDF5 reader? Do I need to install it
from https://bitbucket.org/rhaas80/carpethdf5/src/multifile/ or is there a
newer version?

As to s.screenCapture, it was by default set to 0 , I have attached a
sample image.
setting s.screenCapture = 1 gives empty images, so does not fix the problem.

Best regards,
Atul
