PBE_START_IT No Non-negative integer parameter indicating the iteration from which the nanoparticle/PB model becomes active.
MOMENT_METHOD No Non-negative integer flag specifying the population balance (PB) solution method
NP_DIAM No Non-negative real parameter defining the initial mean monomer diameter of the nanoparticles.
NP_DIAM_MIN No Non-negative real parameter defining the initial minimum monomer diameter of the nanoparticles for the random distribution
NP_DIAM_MAX No Non-negative real parameter defining the initial maximum monomer diameter of the nanoparticles for the random distribution
NP_RHO No Non-negative real parameter defining the density of the solid nanoparticles.
NP_MOLARMASS No Non-negative real parameter defining the molar mass of the nanoparticles species.
NP_VOLUME_FRAC No Non-negative real parameter defining the initial volume fraction of the nanoparticles in the MOM and QMOM methods.
NP_CONCENTRATION No Non-negative real parameter defining the initial number of concentration of the nanoparticles in the MOM and QMOM methods.
