On Construction of the Coarse Space in the BDDC Method

Original language description

The problem of construction of the coarse space for the Balancing Domain Decomposition by Constraints (BDDC) method is discussed. The simple addition of point-wise continuity constraints into the coarse problem is compared with addition of averages overparts of the inter-subdomain boundaries, such as edges and faces of subdomains. The algorithm of BDDC method is presented with emphasis on the coarse space generation. The study contains various results for both approaches applied to elasticity analysisof a turbine nozzle.
