Options

On the Options tab of the Lithology Modelling form, either use Lithology or set Custom parameters for the interpolation.

Custom

Interpolation model resolution

Select a Dynamic, Standard, Fine or Superfine resolution for the output model. The option you select will determine the size of the blocks (grid spacing) for the area of interpolation.

Dynamic is the default option and will automatically adjust the resolution depending on the density of the data model, providing better than Superfine resolution in much less time.

Note that the Dynamic, Fine and Superfine interpolation resolution options may require a modelling parameter file to be stored in your Windows Temp directory and may take up to 1.5GB of space.

Tension

Use the slider to set a tension value between 0 and 100, where smaller values favour smoothness (minimum curvature) and larger values favour accurately honouring the contacts (minimum error). The default is 90.

When Dynamic is the selected resolution option, an Adaptive Tensioning check box option is enabled. Select this option when trying to model problematic data, for example, a surface which undulates very rapidly.

Max Pinch Distance

Enter the maximum distance (from any drillhole) for the seam before it is pinched out. If the application determines that a shorter distance is more appropriate, it will use that distance.
