The error is about material defined by user

Geometry and Materials
1

i do a simulation using material defined by myself, like this:
MATERIAL 32 5.35 ge
LOW-MAT HYDROGEN 32 -2 296 GERMANIU

when running the application, the error occurs:
***** Neutron Xsec: ****
**** Group limits, average energies, velocities and momenta start at location 10226695, end at location 10228862 (I*4 addr.) *****

**** Low energy neutron xsec not found for some media 0 1 ****
ge
it seems i do not add a neutron cross section.

but i add the cross section concerning the material “ge”:
LOW-MAT HYDROGEN 32 -2 296 GERMANIU

by the way, when using material predefined, everything works well.

Dear @Newconcept_1979,
What you are doing with your LOW-MAT card is assigning the low energy neutrons cross sections of Germanium to the material “HYDROGEN”.
You are not assigning any low energy neutron cross sections to the material “ge”.

@ amario, thanks, i got the mistake.
