◆ labelDofManagers()

void oofem::ParmetisLoadBalancer::labelDofManagers ( )

Label local partition nodes (the nodes that are local or shared). Labeling consist of assigning corresponding id that characterize the status of local dof manager after balancing the load. Labeling determines which of local nodes remain local, or became local on other partition, or became shared, etc.
