f = block.proppant.perm.factor
block.proppant.perm.factor = f

Get/set the permeability factor used to used to calculate the permeability of flow zones when one or more vertices has an aperture less than the proppant grain size multiplied by proppant grain size factor. The value is multiplied by the inherent permeability to yield the ‘blocked’ permeability. Default is 0.

Returns:f - proppant blocked permeability factor
Accepts:f - proppant blocked permeability factor
