### 10.9.12. Parts - Zoning - Surface

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.

I/J/K-constant

  Select whether you want to zone a surface with a constant I, J, or K index.

All

  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:

Index (not for All)

  The I, J, or K index for the surface.

I/J/K-straight (not for All)

  Select one of these options if you want surface nodes to be generated along straight I, J, or K lines.

Plane

  Select this option if you want surface nodes to be generated equipotentially in a plane.

Sphere

  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).

Geometric Ratios

  Set geometric ratios in the fields provided if you want to grade the zoning instead of equally spacing the nodes.
