Detailed Description

Represent the abstraction for DOF manager.

This DOF manager is on partition boundary and influences to master equations. It is typically shared by two or more partitions. It keeps its associated global number, number of partitions sharing it, and corresponding number of DOFs (only those with associate equation are taken into account). If n partitions share the DOF manager, then on master level n-1 different code numbers for each DOF must be maintained. The compatibility is then enforced using Lagrange multipliers. It is necessary to select one partition (reference one), to which other partitions DOFs are "linked" through Lagrange multipliers. Such partition contributes to all sharing partitions DOFs. Such partition contribute to all allocated cod numbers. The partition with lowest rank is selected as reference one.

Member Data Documentation

IntArray oofem::FETIBoundaryDofManager::codeNumbers

protected

Contains code numbers for each linked partition for each DOF (ndofs*(numberOfPartitions-1) DOFs).

The reference partition contributes to all code numbers. The code numbers for n-th linked partition (its number is determined by index of corresponding entry in partitions array) are stored at ((n-1)*ndofs+1, ..., n*ndofs) positions in codeNumbers array.
