I'm dealing with some athena data right now, and running into some issues with defining regions.
an example, with domain_left_edge = [0, 0, 0], and right_edge = [1, 1, 1]
In : center=[0.5,0.5,0.5] In : lc = [0,0,0.4] In : rc=[1.0,1.0,0.6] In : region = pf.h.region(center, lc, rc) In : region.volume() Out: -inf
I'm able to get at region.quantities, but trying to make a projection plot fails.
Interestingly, or maybe not, if I try to do something similar with data that has its domain centered on the origin, the volume is finite and everything I've tried with plotting works fine. I guess athena support is still a bit preliminary, but I thought I'd throw this out there.
