Hamideh,

one line of input is not sufficient: you should have sent the whole input f=
ile.
Is METAL the name of a region or of a material?
If it is the name of a material, then be aware that the transport cutoff fo=
r
electrons and photons is set by region, not by material (by material is set=
 the=20
production cutoff, which is not relevant here).
