### 10.13.8. Parts - Solvers (Structured) - Dezone (2D & 3D Euler)

This window lets you dezone a 2D or 3D Euler (Ideal gas) or
Euler (Multi-material) Part.

Dezoning involves combining a number of cells in a fine grid
into single cells of a coarser grid.

**I-factor**The number of cells in the I direction you want to
combine into a single cell. This total number of cells in the I direction
(IMAX-1) must be exactly divisible by this number.

**J-factor**The number of cells in the J direction you want to
combine into a single cell. This total number of cells in the J direction
(JMAX-1) must be exactly divisible by this number.

**Update grid size?**Select **Yes** if you
want the IJ index range of the Part to be reduced automatically to
reflect the dezone. If you select **No**, the index range will remain unchanged, with the higher indexed
cells becoming unused.

**K-factor (3D only)**The number of cells in the K direction you want to
combine into a single cell. This total number of cells in the K direction
(KMAX-1) must be exactly divisible by this number.
