This window lets you zone a surface of the IJK region you selected (i.e. an index plane with I, J, or K constant) from nodes already defined along its four edges.
Select whether you want to zone a surface with a constant I, J, or K index.
Select this option if you want to zone all six outer surfaces of the IJK range you have selected.
The dialog window will then look like this:
The I, J, or K index for the surface.
Select one of these options if you want surface nodes to be generated along straight I, J, or K lines.
Select this option if you want surface nodes to be generated equipotentially in a plane.
Select this option if you want surface nodes to be generated equipotentially on the surface of a sphere (you will be asked to specify the center of the sphere).
Set geometric ratios in the fields provided if you want to grade the zoning instead of equally spacing the nodes.
