Parallel processing for multiple cores / CPUs

Multiple cores are used when factoring the stiffness matrix and when solving for load vectors. These operations occur during the following analyses:

• Linear-static
• Nonlinear-static
• Eigen and Ritz
• Direct-integration time-history
• Influence-based

The following operations are also parallelized:

• Moving-load analysis
• Modal history response recovery
• For nonlinear static and nonlinear direct integration time history cases, nonlinear stiffness formation, event determination, and state update algorithms for the elements below:
  • Frame/Pipe
  • Link
  • Plane/Asolid
  • Solid
  • Shell

A single core is used during modal time-history analysis.

Future CSI  Software releases will offer additional parallel processing capabilities for various software applications.
