7.7. Rebalance Settings
This section is referenced in the following other sections
7.7.1. Combine Rebalance Groups
- Syntax
Combine Rebalance Groups CombinedRebalanceGroups…
- Summary
Specifies a list of rebalance groups to combine into the DEFAULT rebalance group for the equation system. By default, each equation system will be split into the following four rebalance groups: DEFAULT, ASSEMBLY, LINEAR_SOLVE, and CHEMEQ_UTIL. Only the ASSEMBLY and CHEMEQ_UTIL rebalance groups can be combined into the DEFAULT rebalance group. The LINEAR_SOLVE rebalance group uses a non-time based measure of the work load and so can not be combined into the DEFAULT rebalance group. Note that combining rebalance groups may hide load imbalances in the equation system.

7.7.2. Enable Rebalance
- Syntax
Enable Rebalance [ With Threshold Threshold ]
- Summary
Activate rebalance, optionally specifying the rebalance threshold.
Threshold is in terms of the ratio of the maximum (over all processors) cpu time per timestep divided by the average cpu time per timestep. If the observed value of this ratio meets or exceeds the given value, rebalance will be performed.
The default threshold value is 1.25.
7.7.3. Maximum Number Of Nodal Rebalance Iterations
- Syntax
Maximum Number Of Nodal Rebalance Iterations Count
- Summary
Specify the maximum number of nodal rebalance iterations to be performed after a dynamic rebalance.

7.7.5. Rebalance After Adaptivity
- Syntax
Rebalance After Adaptivity
- Summary
Command to automatically execute a rebalance after each solution control adaptivity step
7.7.6. Rebalance Load Measure Type
- Syntax
