This dialog presents individual phases of calculations:
- Model reduction (renumbering of nodes and elements).
- Definition of the stiffness matrix for individual structure elements.
- Matrix decomposition (Cholesky decomposition).
- Number of blocks.
- Division of the stiffness matrix. A part of the matrix is saved on the disk, slowing calculations.
- Problem solving for successive load cases.
The skyline method involves solving the K * x = b linear equation system or the eigenvalue problems Kφ - λB φ = 0 equation system. The stiffness matrix K is decomposed into the matrices
