Hi

When I calculate neutron penetration into iron and concrete materials, it looks like that simulation with LBE physics list frequently enters infinite loop. 
Same calculation with other reference physics list like FTFP_BERT, Shielding does not have this trouble.

I forget to mention that I have this trouble on v10.00.p01 and 10-00-ref-02.

Hello Tatsumi,

why you need LBE list, what is physics reason? This list is not supported as far as I know.

Hi Vladimir,

Actually, I do not need physics list of myself.
However, if we do not support this physics list any more then we should remove from release. 
And I had send other bug report about LBE [#1562] recently, then Luciano made fix quickly.

Hi Tatsumi,
Could you be a bit more explicit as to when the infinite loop occurs?
What energy neutron? After how many events/computation?
Thanks,
Alex

Hi,
Please try tag phys-lists-V10-00-07 it should now be okay, I hope.
