cylinders

Fit model: cylinders

Parameters:

parameter	description
F_scal	scaling parameter (should be between 0.1 and 10 - see here)
F_rad	cylinder radius
F_sigma	polydispersity index [0,1]
F_height	cylinder length
S_phi	volume fraction

Remarks:

the model performs a single numerical integration to take into account for the size distribution;

the averaging for different orientations of the cylinders is done by averaging 150 models with continuously varying orientation between 0 and 90 deg

a Gaussian size distribution is used by default
