"Moments" app doesn't seem to exist

[skylord-a52]

My setup is able to run VlasovMaxwell and Gyrokinetic apps just fine.

However, trying to run any of the given example scripts for Euler/Ten-moment sims gives the following error:

> gkyl rt-10m-gem.lua
*** LOAD ERROR ***
 [string "-- Gkyl -------------------------------------..."]:2: attempt to call field 'Moments' (a nil value)

I set up this small test script.

local Apps = require("App.PlasmaOnCartGrid")

for key,value in pairs(Apps) do
    print(key, value)
end

Running it through gkyl gives the following:

> gkyl test.lua
Gyrokinetic     function: 0x7fe173393770
VlasovMaxwell   function: 0x7fe1733937e0

There's no entry for a Moment app! Somehow, my version of Gkeyll only has VlasovMaxwell and Gyrokinetic apps available. Redownloading and rebuilding Gkeyll didn't help.

Please see this note in the Gkeyll documentation. If you are running things through G2 you have to switch to the pre-g0 branch. The updated fluid solver should be back into G2 using the gkylzero library directly in the next few months, but you can use the older fluid solver in the pre-g0 branch.

You can also run the fluid solver directly through the gkylzero library if you are comfortable with just running C input files directly (https://github.com/ammarhakim/gkylzero). We are working on re-integrating the Fluid solver functionality from the improvements of the gkylzero library but just haven't completed the Lua-C wrapping.

Ah, my bad, I missed that! Thank you.
