### 10.9.13. Parts - Zoning - Volume

This window lets you zone the interior volume of the IJK region
you selected from nodes already defined on its six faces.

**IJ-straight**Select this option if you want to generate the interior
volume so that nodes with the same (I,J) indices lie equally spaced
along a straight line

**JK-straight**Select this option if you want to generate the interior
volume so that nodes with the same (J,K) indices lie equally spaced
along a straight line

**IK-straight**Select this option if you want to generate the interior
volume so that nodes with the same (I,K) indices lie equally spaced
along a straight line

**Autozone**Select this option if you want to generate the interior
volume so that all nodes are spaced equipotentially.

**Geometric Ratio**Enter a geometric ratio in this field if you want
to grade the zoning instead of equally spacing the nodes.
