#2744: Cactus: New cGH entries `cctk_level`, `cctk_block`
Reporter: Erik Schnetter
Status: new
Milestone:
Version:
Type: enhancement
Priority: major
Component: Cactus
Add new `cGH` entries `cctk_level` and `cctk_block`. These complement the existing `cctk_patch` and `cctk_tile_{min,max}` fields, and allow the compute kernels to know on which part of the grid structure they are operating. This is mostly interesting for producing better debugging output.
There are also new `#define`s `CCTK_HAVE_CGH_LEVEL` and `CCTK_HAVE_CGH_BLOCK` to indicate that these new fields are present.

#2485: include complex and real scalar evolution code from Canuda in ET
Reporter: Roland Haas
Status: open
Milestone:
Version:
Type: task
Priority: major
Component:
Comment (by Roland Haas):
Thank you. One question the ScalarBase \(and Evolve I guess\) docs show:

and state that this is the Klein-Gordon evolution equations. I guess it could be given that the evolution equations for Phi \(which I would naively think of the Klein-Gordon equations\) follow from requiring the Bianchi identities to hold for Gmunu. Maybe it would still be useful to spell out the Box Phi equation?
There are various rendering issues with the TeX files on the webserver:

and also in TwoPunctures:
and

These are sometimes caused by “dodgy” TeX \(eg leaving out `{}`\) and sometimes, unfortunately, by issues with the TeX to HTML conversion, which can even be converter version dependent. I will take a look at those rendering issues and create pull requests for any non-invasive workarounds that I find.
