Dear Adam,
if you check the output file, you will see that Fluka cannot run
because you have forgotten to define how low energy neutrons should
treat your new compound: you need a LOW-MAT card for each of your
MO isotopes to associate them to the material present in the Fluka
database (in this case natural Molybdenum as best proxy).
In case of a single element, since the material name is equal to the
low energy neutrons name in the database, no extra card is required
and the association is done automatically.
Everything is explained in the LOW-MAT card entry and in chater
10 of the Fluka manual.
I attach a revised version of your input that should run.
Kind regards,
Andrea
