[CIG-MC] ConMan issues report

Wed Aug 17 16:12:33 PDT 2016

I'd be curious how the speed of Aspect in 2D benchmark tests compares with
ConMan for high Ra cases. From Aspect cookbook cases my student ran a while
back it seemed the Aspect was quite resource demanding for high Ra at
comparable resolved structure, though there might have been some user
error.
