This command selects as a parameter a grid scaling factor. Nodal distances, interface areas, and gridblock volumes will be scaled accordingly. There are three grid scaling factors, referring to the three directions specifed by TOUGH2 variable ISOT. The direction is selected through command >>>> INDEX. If all three directions are selected, the mesh is scaled isotropically (see TOUGH2 variable SCALE).
Selecting a grid scaling factor as a parameter can be used to design and optimize the horizontal and/or vertical spacing between injection points.
