# 3.3. Other Subcycling Issues

In parallel, subcycling will perform best if a mesh rebalance is performed to ensure both the fine and coarse regions are divided evenly among the processor sets. A mesh rebalance command similar to the one below can be used to automatically performance such a mesh rebalance. See the Sierra/SM User Manual for more information on mesh rebalancing.

    BEGIN REBALANCE
      PERIODIC REBALANCE = AUTO
      DELETE DEACTIVATED ELEMENTS AFTER REBALANCE = ON
    END
