Original language description
Software EA-AMG for parallel solution of 3D boundary value problems of linear elasticity. The software is based on the FEM and the corresponding linear system of algebraic equations is solved by the preconditioned conjugate gradient method with the additive two level overlapping Schwarz preconditioner. The stiffness matrix for the coarse problem is created by a new aggregation technique. Both Dirichlet and Neumann boundary conditions can be applied. In the second case, arising singular system can be efficiently solved making use of projections. Software package contains two codes. The code AGGREG serves for preparation of an aggregated matrix. The code SOLVER_AG is designed for the parallel solution of large linear systems and is parallelized with theaid of OpenMP paradigm.
