Recently I made the Maestro BoxLib frontend set the correct boundary periodicity for a data set, and I can confirm this when I load the data in yt and look at periodicity. However, when I try to volume render, with no_ghost=False, I get an error in the non-periodic direction (we are periodic in x and y, and non-periodic in z).

The error is:

Error: bad Region in non-periodic domain: -24.0 code_length 0.0 code_length 408.0 code_length 4608.0 code_length

for reference, the domain size is:

Parameters: domain_left_edge = [ 0. 0. 0.]

Parameters: domain_right_edge = [ 1536. 1536. 4608.]

(aside, these should be cm, but the error reports them as code_length -- should I be setting that somwhere in the frontend? we are always CGS).

I can't speak to the volume rendering issue but this is the as-designed behavior. This has to be code_length because other codes do not have CGS as the internal unit system and this code has to work for all frontends, irrespective of the internal unit system.

Any thoughts on what I may be missed setting up for non-periodic BCs is appreciated.
