fdenc = fracture.centerdensity(<vlower><,vupper><,dfn>)

Get the fracture center density. The fracture center density is defined as the {P20 value in 2D; P30 value in 3D} as measured in the specified region. {P20 in 2D; P30 in 3D} is the number of fracture centers in the specified region per unit area (volume). If dfn is not given the calculation is undertaken over all fractures of all DFNs.


fdenc - fracture center density value


vlower - optional lower bound of the calculation region

vupper - optional upper bound of the calculation region

dfn - optional DFN pointer
