[Flash-X-users] Getting Flash-X to work

[Peter Manzella]

I am having trouble understanding this. I am trying to call it, as I
understand "call it" I type that into the command line and press enter,
that is not working for me, is there something I am missing? I am also not
seeing any of those tests in thornado that you suggest running.
I feel like there is some gap in how I am supposed to use Flash-X, is there
a primer on some basics? I was suggested to use Flash-X after having spent
months trying to use FLASH for 2d simulations after being told that it
could do so, going from that one to this one is not intuitive as there are
many more moving parts with no documentation (at least that I could see)
for that.
