### 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.
