Detailed Description

The Sierra Toolkit Rebalance package supports computing a new mesh partition to reduce computational load imbalance and the corresponding migration of mesh entities to the new partition. Contents are as follows

• Unit Tests

• Use Cases

How to build stk with Rebalance enabled.

The stk_rebalance capability is enabled in a Trilinos build that has been configured with the Zoltan and STK pacgakes enabled, eg

      cmake \
        .... other cmake options ....

        -D Trilinos_ENABLE_STK:BOOL=ON \
        -D Trilinos_ENABLE_Zoltan:BOOL=ON \

        .... other cmake options ....
