Analysis Capabilities

Linear equation solvers, time integration schemes, and solution algorithms are the core of the OpenSees computational framework. The components of a solution strategy are interchangeable, allowing analysts to find sets suited to their particular problem.

Eigenvalue Solvers

The following methods provide the solution of the generalized eigenvalue problem \(Kv = MvL\)

• Symmetric Arpack – Arpack solver for symmetric matrices
• Band Arpack – Arpack solver for banded matrices
