Hi all. I looked for VisIt-related queries, but couldn't see a good match for this issue:
I'm trying to visualize (Pseudocolor) a grid function output in 2D by CarpetIOHDF5. I've done this many times for scalar grid functions in the recent past, and it's worked fine. However, now the field I'm looking at is one of the components of (HydroBase::vel) , and it's giving me problems.
Data read-in, Add -> Pseudocolor, and Operators -> Project generate no error messages. However, when I click on "Draw"., I get the error: ------------------------------------------------------------------------------------ Pseudocolor: () viewer: An invalid variable (HYDROBASE--vel[0]) was specified ------------------------------------------------------------------------------------
This is the only time I've tried to plot a *vector* grid function component. Most other GF groups (those in ADMBase, for instance) work as three *scalar* grid functions, and I've had no problem with their components in VisIt.
Do you have any ideas what's going wrong? Is VisIt being confused by the "[0]" in the variable name in the HDF5 metadata?
I've tried this with all components in one HDF5 file (one_file_per_group = "yes") and in separate files, with no difference.
I've also tried making a new, simpler-named variable using Controls -> Expressions, but VisIt then complains when trying to select this data at the "Add -> Pseudocolor" stage.
[My VisIt version is 2.8.2, and I'm still working with ET release ET_2014_05.]
Thanks,
Bernard
Hello Bernard,
I'm trying to visualize (Pseudocolor) a grid function output in 2D by CarpetIOHDF5. I've done this many times for scalar grid functions in the recent past, and it's worked fine. However, now the field I'm looking at is one of the components of (HydroBase::vel) , and it's giving me problems.
Try: HYDROBASE--vel_lb_0_rb_
visit began replacing invalid characters with substitutions (_rb_ = right bracket?).
You can also find the correct name in the variables (Scalar) drop down box of the expression editor (near the bottom right, next to the functions drop down).
Yours, Roland
Hi Roland.
Thanks --- actually when I start with "Add -> Pseudocolor", what appears in the available fields *is* "HYDROBASE--vel_lb_0_rb_"
Nevertheless, when I try to *draw* the resulting plot, the error message talks about the bracketed version, "HYDROBASE--vel[0]". So perhaps this version of VisIt isn't being consistent with the bracket to "lb/rb" substitution?

Hi Beany, I use Visit 2.8.0 and I don’t have problems visualizing one of the components of the velocity (in my case each components is saved in a different hdf5 file). Can you try using this older version of Visit and see if you still get the same error?
Cheers, Bruno

Hi Bruno.
Aha! VisIt 2.8.0 *works*, but 2.8.2 *doesn't*.
Gah. I suppose I should tell them they've broken something.
Thanks,
Beany

Hello Bernard, Bruno,
Aha! VisIt 2.8.0 *works*, but 2.8.2 *doesn't*.
Gah. I suppose I should tell them they've broken something.
2.8.2 works for me (at least the version that I compiled myself, and reading in a 2d hdf5 file hydrobase::vel.xy.h5).
Yours, Roland
I'm using the pre-compiled OSX binary. So perhaps it was in the packaging?

Oh, I should mention that I saw the same problem with the pre-compiled 64-bit version for Red Hat Linux.
