The Selection of Fixing Nodes in FETI-DP Method Using Graph Theory
Original language description
The contribution deals with selection of fixing nodes in FETI-DP method. Fixing nodes are used to enforce continuity conditions on subdomain boundaries and non-singularity of subdomain and coarse matrices. The graph theory is applied for selection of such nodes. Interface nodal graph is created from interface nodes. Degree of vertex is established for each vertex of graph. The fixing node is selected as the vertex with degree of vertex equal to one or greater than two. Geometrical control of basic fixining nodes is performed after selection procedure. The number of fixing nodes can be increased by extended algorithm. Algorithm was successfully tested on several numerical examples.
