IFZ fractures (*.ifz)

The format of the file is:

  1. A line containing the fracture name;
  2. A line containing number of points (max 10) defining the fracture (np)
  3. np lines giving the coordinates of the points defining the fracture (the fracture plane will be defined by the first 3 points)
  4. A line giving the thickness of fracture;
  5. A line giving the number of depth intervals (nd), a flag indicating whether fracture is stochastic (1) or deterministic (0), correlation length on the fracture (0.0 if deterministic), discretisation length of the fracture (0.0 if deterministic)
  6. A line (if nd=0) or nd lines giving the < bottom of depth zonation >, longitudinal flow parameter, transverse flow parameter, porosity, < flow wetted surface >, < spread in logarithm (base 10) of flow parameter >. (number of depth intervals rows)
Note: Optional input is enclosed in < > brackets; Points should be coplanar, but a fractures may be trapezoidal, triangular, or polygons;

x, y and z corrdinates should be in metres and z is elevation.
