Selection strategy for fixing nodes in FETI-DP method

Original language description

This contributions deals with selection strategy for fixing node selection. Fixing nodes ensure non-singularity of subdomain matrices in FETI-DP method. Selection of fixing nodes is based on nodal multiplicity (the number of subdomains which share the node). At the end of contribution there is numerical example for 2D test. This example shows that increasing of fixing nodes leads to decreasing of the number of iterations, but big number of fixing nodes leads to prolongation of whole time of solution.
