[Users] multipatch visualization of Thornburg04

Hi,

I’m trying to create a multipatch visualization using VisIt’s GUI (version
3.1.4, on MacOS). I am following the tutorial

https://docs.einsteintoolkit.org/et-docs/GW150914_VisIt_Tutorial

which allows me to correctly visualize the Cartesian portion of the grid as
in the provided example.

However, I am unable to visualize the spherical part of the grid, which, if
I understand correctly, should be in the data since the grid settings in
the parfile include

Carpet::domain_from_multipatch          = yes
CartGrid3D::type                        = "multipatch"
CartGrid3D::set_coordinate_ranges_on    = "all maps"
Coordinates::coordinate_system          = "Thornburg04"

For concreteness, let’s say we are working with the data from the file
`phi.0.xy.h5`. Taking some hints from the thread

http://lists.einsteintoolkit.org/pipermail/users/2019-January/006716.html

it seems that the coordinate files `x.0.xy.h5`, `y.0.xy.h5`, `z.0.xy.h5`
are required to visualize the spherical part of the grid, so I open all of
these files before doing, say, Add > Pseudocolor > ML_BSSN_phi.

This produces the Cartesian portion of the grid. I’ve tried looking for the
option "Carpet Multipatch” but it doesn’t seem to be available.

Any recommendations?

Thank you!
Tomas
