Christian Jakob posted a new comment:
It is not double-checked, but quad-checked (maybe even more).

YADE input file:

#GENERAL SETTINGS:
initial_porosity		= 0.4
shear_modulus			= 3e7
poisson_ratio			= 0.3
young_modulus			= 2*shear_modulus*(1+poisson_ratio)
friction_coeff			= 2
angle					= math.atan(friction_coeff)
rho_p					= 2650	#density of particles

#SET DAMPING CONSTANTS:
local_damping			= 0.01
viscous_normal			= 0.021
viscous_shear			= 0.8*viscous_normal

PFC input file:

	;GENERAL SETTINGS:
	initial_porosity		= 0.4
	shear_modulus		= 3e7
	poisson_ratio		= 0.3
	friction_coeff		= 2
	rho_p				= 2650	;density of particles

	;SET DAMPING CONSTANTS:
	local_damping		= 0.01
	viscous_normal		= 0.021
	viscous_shear		= 0.8*viscous_normal

The only thing I could imagine, that is wrong, is

young_modulus                   = 2*shear_modulus*(1+poisson_ratio)

but wikipedia tells me this is ok...
