Dear Dr. Fasso
Thanks indeed for your instant reply. if we enter lung(ICRP) with the
density of 1.05 g/cm3 from flair material data library to the input
file and do not define MAT-PROP, does the code consider the 0.3 g/cm3
average density for the lung automatically? I mean for defining the
lung with 0.3 g/cm3 average density, is it necessary to
define MAT-PROP card in the input file?
Best Wishes,
