As of V14.1.0, multi-cores are used when factoring the stiffness matrix and solving the load vectors. This would occur during linear static analysis, Eigen and Ritz analysis, nonlinear static and direct-integration time-history, and influence-line analysis. Once the modes are found, modal time-history analysis currently uses a single core. Similarly, moving-load analysis uses a single core. Adding additional parallel processing capabilities for different parts of the program is planned for a future releases. See also parallel processing in Ritz vector analysis.
