Source / Independent Source

[cfichtlscherer]

Hey Julien,

In OpenMC Source has been renamed to IndependentSource, this is not yet part of OpenMC 0.13.3, but already in the developement branch and will be part of OpenMC 0.13.4. So it should be updated, I think.

Compare: openmc-dev/openmc#1706

Simply changing Source to IndependentSource worked for me.

Not sure whats the best strategy to enable users with different OpenMC versions to run ONIX.

Maybe you could add something like:

if openmc.__version__ > 0.13.3:
     .... IndependentSource ....
else:
    ..... Source ....

An alternative would be using try: and except AttributeError:

I hope this helps a bit 😃
