Re: question on ROT-DEFI

Dear Chris and Francesco,

thanks a lot for your prompt response and explanation. I have modified
my geometry in order to use only allowed nested structures and, as
expected, everything works fine. However, It should be good to modify
flair (geometry editor) in a way which will help to avoid the
utilization of structures that don't work in fluka.

Cheers,
Jan
