### 10.15.4. Parts - Motions - Modify

This window lets you change ALE settings.

**Spacing**The geometric ratios for spacing of I, J, and K lines.
These are used only for certain motion constraints.

**Frequency****Cycle Frequency**Enter how often (in cycles)
you want ALE rezoning to be performed.

**Iterations per cycle**Enter the number
of iterations you want the ALE solver to perform in converging to
the spacing you have requested. This is used for all motion constraints
except **Fixed (Euler)**.

**Relaxation coefficient**Enter the relaxation
coefficient you want to use for the ALE rezoning.

A value
of 1.0 will move each node exactly to the location required for its
motion constraint.

A value of 0.5 will move each node 50% of the distance towards
the location required for its motion constraint.
