Specifies the thickness of the material inserted into the DD element (i.e. fault gouge, seam width, mining width or pillar height).
Normal displacement (closure) of the feature when in-filled will be limited to this thickness. Also, the normal displacement (closure) and shear displacement (ride) are divided by the thickness to determine the strain occurring in the in-filling material.
This parameter should be specified in the same units used to specify the coordinate positions (e.g. metres or feet). This parameter is not used for 3D FF blocks.
