[Users] Warning: Cannot output variable because it has no storage (ADMAnalysis OR ADMMass)

[刘屿]

Hello Cactus users,

I am new to Einstein Toolkit. I want to write a simple parameter file,
according to my understanding of Thorn. When I use the Thorn in
EinsteinAnalysis, I encountered a warning (Level 1) and CarpetIOBasic can't
output normally.

I couldn't find the reason for the warning, because the warning message is
brief.

I also want to know the difference between output-0000 and
output-0000-active in simulation directory.

Thanks,
